#REDIRECT Time zone
::''Time Zone (computer game) is also a historical computer game.'' ::''There is also an Australian franchise of video arcades called Timezone (video arcades).'' Time zones are areas of the Earth that have adopted the same standard time, usually referred to as the local time. Formerly, people used local solar time (originally apparent and then mean solar time), resulting in time differing slightly from town to town. As telecommunications improved and with the expansion of the Rail transport this became increasingly awkward. Time zones partially rectified the problem by setting the clocks of a region to the same mean solar time. Time zones are generally centered on Meridian (geography)s of a longitude that is a multiple of 15 thus making neighboring time zones one hour apart. However, the one hour separation is not universal and, as the map below shows, the shapes of time zones can be quite irregular because they usually follow the boundaries of states, countries or other administrative areas. All time zones are defined relative to Coordinated Universal Time (UTC). The reference point for Time Zones is the Prime Meridian (longitude 0) which passes through the Royal Greenwich Observatory in Greenwich, London, United Kingdom [http://greenwichmeantime.com/]. For this reason the term Greenwich Mean Time (GMT) is still often used (by the BBC, for example, amongst others) to denote the "base time" to which all other time zones are relative. UTC is, nevertheless, the official term for today's atomically measured time as distinct from time determined by astronomical observation as formerly carried out at Greenwich. GMT (UTC) is, incidentally, local time at Greenwich itself only between 01:00 UTC on the last Sunday in October and 01:00 UTC on the last Sunday in March. For the remainder of the year local time is UTC + 1—known in the United Kingdom as British Summer Time (BST). The time for a location is given relative to UTC. Some examples: *Los Angeles, California, California, United States: UTC − 8 (e.g. if it is 12:00 UTC, then it is 04:00 in Los Angeles) *Toronto, Ontario, Ontario, Canada: UTC − 5 (e.g. if it is 11:00 UTC, then it is 06:00 in Toronto) *Stockholm, Sweden: UTC + 1 (e.g. if it is 12:00 UTC, then it is 13:00 in Stockholm) *Istanbul, Turkey: UTC + 2 (e.g. if it is 03:00 UTC, then it is 05:00 in Istanbul) *Mumbai, India: UTC + 5.5 (e.g. if it is 13:00 UTC, then it is 18:30 in Mumbai) *Tokyo, Japan: UTC + 9 (e.g. if it is 11:00 UTC, then it is 20:00 in Tokyo) Where the adjustment for time zones results in a time the other side of midnight from UTC, then the date at the location is one day later or earlier. Some examples: *Cairo, Egypt: UTC + 2 (e.g. if it is 23:00 UTC on Monday 15 March, then the time in Cairo is 01:00, Tuesday 16 March) *Auckland, New Zealand: UTC + 12 (e.g. if it is 21:00 UTC on Wednesday 30 June, then the time in Auckland is 09:00, Thursday 1 July) *New York, United States: UTC − 5 (e.g. if it is 02:00 UTC on Tuesday, then the time in NY is 21:00 on Monday) *Honolulu, Hawaii, USA: UTC − 10 (e.g. if it is 06:00 UTC on Monday 1 May, then the time in Honolulu is 20:00, Sunday 30 April) Note: The time zone adjustment for a specific location may vary due to the use of daylight saving time. *e.g. New Zealand which is usually UTC + 12, observes a one-hour daylight saving time adjustment during the southern hemisphere summer resulting in a local time of UTC + 13! See also: Sidereal time Calculating local time ==History== The first time zone in the world was established by British railways on December 1, 1847—Greenwich Mean Time (GMT) being hand carried on chronometers. About August 23, 1852, time signals were first transmitted by telegraph from the Royal Greenwich Observatory. Even though 98% of the Great Britain's public clocks were using GMT by 1855, it was not made Britain's legal time until August 2, 1880. This paragraph only applies to the island of Great Britain, not to the island of Ireland. On November 2, 1868, New Zealand officially adopted a standard time to be observed nationally, and was perhaps the first country to do so. It was based on the longitude 172 30' East of Greenwich, that is 11 hours 30 minutes ahead of Greenwich Mean Time. This standard was known as New Zealand Mean Time. Multiple time zones were first proposed by Charles F. Dowd about 1863 for American railroads as a teacher to his students. In 1870, after consulting railroad officials in 1869, he proposed four ideal time zones, the first centered on Washington, DC, but by 1872 the first was centered 75W of Greenwich with geographic borders. American and Canadian railroads implemented their own version on Sunday, November 18, 1883, when each railroad station clock was either advanced or delayed as noon, standard time, was reached within each time zone, east to west. The zones were named Intercolonial, Eastern, Central, Mountain, and Pacific. Within one year, 85% of all cities having populations over 10,000, about 200 cities, were using standard time. A notable exception was Detroit, Michigan, which kept local time until 1900, then vacillated between Central Standard Time, local mean time, and Eastern Standard Time until it settled on EST by ordinance May 1915, ratified by popular vote August 1916. This hodgepodge was made uniform when Standard zone time was made legal by the Congress of the United States in 1918. Time zones were first proposed for the entire world by Canada's Sir Sandford Fleming in 1876 as an appendage to the single 24-hour clock he proposed for the entire world (located at the center of the Earth and not linked to any surface meridian!). In 1879 he specified that his universal day would begin at the anti-meridian of Greenwich (now called 180), while conceding that hourly time zones might have some limited local use. He continued to advocate his system at subsequent international conferences. In October 1884 the International Meridian Conference did not adopt his time zones because they were not within its purview. The conference did adopt a universal day of 24 hours beginning at Greenwich midnight, but specified that it "shall not interfere with the use of local or standard time where desirable." Nevertheless, most major countries had adopted hourly time zones by 1929. Even today, they have not been fully realized, with several time zones keeping a standard time that is not offset by a number of whole hours from Greenwich Mean Time. Before 1920, all ships kept local apparent time on the high seas by setting their clocks at night or at the morning sight so that, given the ship's speed and direction, it would be 12 o'clock when the Sun crossed the ship's meridian (12 o'clock = local apparent noon). During 1917, at the Anglo-French Conference on Time-keeping at Sea, it was recommended that all ships, both military and civilian, should adopt hourly standard time zones on the high seas. Whenever a ship was within the territorial waters of any nation it would use that nation's standard time. The captain was permitted to change his ship's clocks at a time of his choice following his ship's entry into another time zone—he often chose midnight. These zones were adopted by all major fleets between 1920 and 1925 but not by many independent merchant ships until World War II. Time on ship's clocks and in a ship's log had to be stated along with a "zone description", which was the number of hours that was to be added to zone time to obtain GMT, hence zero in the Greenwich time zone, and negative numbers from −1 to −12 for time zones to the east and positive numbers from +1 to +12 to the west (hours, minutes, and seconds for nations without an hourly offset). These signs are opposite to those given below because ships must obtain GMT from zone time, not zone time from GMT. All zones were pole-to-pole staves 15 wide except for −12 and +12, which were each 7.5 wide separated by a longitude of 180. Unlike the zig-zagging land-based International Date Line, the nautical International Date Line follows 180 except where it is interrupted by territorial waters and the lands they border, including islands. About 1950, a letter suffix was added to the zone description, assigning Z to the zero zone, and A-M (except J) to the east and N-Y to the west (J may be assigned to local time in non-nautical applications). These were to be vocalized using a NATO phonetic alphabet which included Zulu for GMT. These nautical letters have been added to some time zone maps, like the map of [http://aa.usno.navy.mil/faq/docs/world_tzones.html Standard Time Zones] by Her Majesty's Nautical Almanac Office (NAO), which extended the letters by adding an asterisk (*) or dagger (typography) (†) for areas that do not use a nautical time zone, and a double dagger (‡) for areas that do not have a legal standard time (Greenland's ice sheet and all of Antarctica—Britain specifies UTC − 3 for the Antarctic Peninsula, but no other country recognizes that). They conveniently ignore any zone that does not have an hour or half-hour offset, so a double dagger (‡) has been co-opted for these zones below. In maritime usage, GMT retains its historical meaning of UT1, the mean ''solar'' time at Greenwich. UTC, ''atomic'' time at Greenwich, is too inaccurate, differing by as much as 0.9 s from UT1, creating an error of 0.4 km in longitude at the equator. However, DUT can be added to UTC to correct it to within 50 ms of UT1, reducing the error to only 20 m. == List of time zones and contained areas == Regions marked with asterisks (* or **) observe Daylight Saving Time: add 1 hour in summer (* for Northern Hemisphere summer; ** for Southern Hemisphere). Some zones north-south of each other in the mid Pacific differ by 24 hours in time: they have the same time of the day but differ by a full day. The two extreme time zones on Earth (both in the mid Pacific) differ by 26 hours. A particular day starts earlier in countries with a more positive UTC offset. Thus the first occurrence of a date will be in UTC + 14 and the last of the same date in UTC − 12 (at sea). This gives the interesting feature that during one hour each day there are three different dates in use on land around the world, at 10:30 UTC Monday it is already 00:30 Tuesday in the Line Islands (UTC + 14) while the time is 23:30 Sunday in Samoa (UTC − 11) [http://www.timeanddate.com/worldclock/full.html?sort=2]. Stations in Antarctica generally keep the time of their supply bases, thus both the Amundsen-Scott South Pole Station (U.S.) and McMurdo Station (U.S.) use New Zealand time (UTC + 12 southern winter, UTC + 13 southern summer). Time zone abbreviations are almost always customary, not legal—those listed here only exist in English and are somewhat arbitrary. English time zone names below generally only apply to English speaking areas. The CIA and NAO disagree on the time kept by some Russian oblasts, so both are given below—this may be due to a recent time zone change. === UTC − 12 Y=== Only ships at sea within 7.5 east of 180.

Please delet the "The Time around the World" link. Some times there are wrong. In Paris is a winter/summer time. The page doesn't know that. So the time on the page if one hour to early (Sorry for my bad English) --------------------- So brazil adds an hour (daylight savings time) during whose summer? Dec/Jan summer, or the Northern hemisphere's summer?
~ender 2003-09-12 06:53:MST :Brazil adds an hour only in the southern portions of its time zones during the southern hemisphere summer--no DST in the equatorial regions. -- User:Joe Kress 06:06, 2004 Apr 20 (UTC) So, uh, Spain has both UTC and UTC+1 time? At the same time, no less. How's that? ~Marnevel Is Argentina UTC-4 (text) or UTC-3 (map)? User:Psb777 00:56, 3 Mar 2004 (UTC) :Both of these points were corrected by someone. -- User:Joe Kress 06:06, 2004 Apr 20 (UTC) Not all parts of Brazil incorporate summer time. For the most part, only the southern part of Brazil observes summer time. Some towns will however incorporate summer time if there is an energy shortage. But the closer you get to the equator and the further you get into the Amazon, the fewer the towns that use summer time. Additionally, the dates from when summer time starts to when it ends can change from year to year. Each year the government will determine when and if summer time will be used. Summer time can begin anywhere from the beginning of October to the beginning of November. Summer time can end anywhere from early February to early March. As for Argentenia, is UTC -3 hours and summer time (daylight saving time) is not currently used. User:ganteng ==What about Universal Time Zones?== Someone smarter than me needs to incorporate elements from [http://www.virtualtravelog.net/entries/000031.html this article] about the difference between Universal time zones and Local Civil time zones. And are things like "MSK - Moscow Time Zone" an internationally recognized designation? Saudi Arabia is in that zone, but I doubt they discuss Moscow much. User:Mackerm 22:30, 25 Mar 2004 (UTC) :The referenced article has several errors, the major being that there is no international treaty concerning time zones. These 15 'International Time Zones' were proposed by Fleming, but were assigned these letters only after WWII (Fleming used a different letter system). They may be applicable somewhere, like on the high seas and over radio--they do not legally exist over land (I even have my doubts about the 'military' explanation). Rather, each country specifies its own time zones as it sees fit. Many (most?) time zone abbreviations are customary, not legal. For example, EST, EDT, etc. in the United States are customary only--only full words appear in the US time zone law: [http://www4.law.cornell.edu/uscode/15/ch6schIX.html U.S. Law 15USC260-267]
User:Joe Kress 06:06, 2004 Apr 20 (UTC) ::Thanks for the U.S. law. It prompts another question which has been bothering me about this page: Some of the zones include the word "Zone" in their names, and some don't, e.g., "Bering Standard Time" vs. "Hawaii-Aleutian Standard Time Zone". In examining the U.S. code, I never saw the words "Eastern Standard Time Zone". But since multiple countries on a longitude can pick their own names, it seems a losing battle anyway. User:Mackerm 07:15, 21 Apr 2004 (UTC) :::The zone codes (such as "ZULU") are most assuredly of military origin - I used them all the time in the service. In communications the message is always dated by ZULU/UTC/GMT, and local time was often referred to when documenting events using the local zone code (i.e. "ROMEO" or "UNIFORM" for the U.S. West Coast). These zone codes are standardized throughout the U.S. military, and are part of NATO standardization. :The military may or may not have assigned letters (like Z, R, and U) to the time zones. But I am certain that their pronunciation (like ZULU, ROMEO, and UNIFORM) was NOT developed by any military — the International Civil Aviation Organization (ICAO) developed it between 1947 and 1956. Military aircraft and radio have to use it because their countries are members of the ICAO (and the International Telecommunication Union ITU). NATO had nothing whatsoever to do with 'standardizing' the alphabet, because it does not appear in any NATO publication, and I have looked through many NATO publications trying to find it. If you know of such a NATO publication, please reveal its title. For a more detailed history see the NATO phonetic alphabet.

::Underlining is obtained via underlining . A significant problem with underlining is that it is easily confused with Wikipedia:Glossary#Ws. Such highlighting would not accomplish its purpose here if the main country still appears directly above the possession. Thus I recommend deleting the independent country directly above the possession and no longer indenting the possession. Anyone unfamiliar with the possession can simply follow its wikilink to find its ruling independent country. The independent country for those without wikilinks can be indicated in parentheses. This would work for isolated possessions, but if several possessions or states are in a single time zone the heading serves a useful purpose by collecting them, especially those possessions that are unfamiliar, like Russian oblasts. So I don't recommend deleting the heading for multiple possesions like states. — User:Joe Kress 07:48, Jan 29, 2005 (UTC)
small remark: russian oblasts are not possessions, but administrative divisions, similar to US states, german Lnder, or various provinces. But the argument remains valid, large countries lay in several timezones, but its divisions usually in one zone. Peter.

== Local time ==
I recently added local time as a redirect to time zone, and subsequently bolded local time in the article, on the presumption that it is a common phrase used in reference to the time at a particular location, and is appropriate in many contexts to refer to such a time. (For example, the local time in Brisbane, Australia, is 10:23 PM.) I would just revert to my previous edit, but the calculating local time article leaves me a little unsatisfied (I considered redirecting ''local time'' to there, but ''time zone'' seemed closer to the usual meaning). Could anyone comment on the relationship between the above-mentioned articles? User:Bjcairns 12:29, 28 Jan 2005 (UTC).
:Calculating local time was apparently written by the same person who began the time zone article because of the similarity between them. Moreover, I see no need for ''calculating local time'' — subtracting one time zone from another seems to be so obvious as to not need explanation. I recommend merging ''calculating local time'' into ''time zone'' by simply adding one sentence about it to ''time zone'', leaving ''calculating local time'' as a redirect itself. — User:Joe Kress 07:48, Jan 29, 2005 (UTC)
I agree. Meanwhile, I've put local time back in with a minor edit. User:Bjcairns 00:33, 31 Jan 2005 (UTC).
:If you look at other pages, the only phrases bolded in the introduction are ones that are redirects to the same page. It is a formatting thing, according to the Wikipedia:Manual of Style: ''If the subject of the article has more than one name, each new form of the name should be in bold on its first appearance''. Unless the subject (i.e. time zones) is also named "local time" then it should not be bolded lest it be confused that it might be an alternate name for the article.-- 23:15, 31 Jan 2005 (UTC)
Hi :) The italicised version reads just fine except that local time ''is'' in fact a redirect (give it a try; I put it in myself before bolding it the first time). Sorry, I should have been more clear in my edit summary when I changed it back. I couldn't find a policy on bolding redirects that weren't synonyms, but I've reverted it back to bold because it doesn't look like a separate ''local time'' article is likely (or desirable) any time soon, and I believe it's a legitimate thing that people might want to look up. Bolding it indicates that this is the article in which it is discussed. I won't change it again, but there are my reasons. Cheers, User:Bjcairns 23:29, 31 Jan 2005 (UTC).
:Sorry, completely my fault. It is just that it doesn't appear on "what links here" page. I guess there are over 500 pages that link to Time Zone. I did look over that list twice. My appolgies. -- 05:41, 1 Feb 2005 (UTC)

== UTC vs GMT ==
The article implies that UTC and GMT are the same. I don't believe that this is the case. IIUC, GMT is defined as a number of days (rotations of the earth relative w.r.t. the sun) and UTC is defined as a number of SI seconds (oscillations of cesium atom, or some such thing). I think that the following link may explain the difference:
http://www.faqs.org/faqs/astronomy/faq/part3/
Also, as someone has commented already, the GMT article explains the difference. -- User:Wmarkham 16:10, 3 May 2005 (UTC)
:In my opinion, everywhere that the article implies that GMT and UTC are the same is appropriate. They are indeed synonyms as far as the BBC is concerned as the article states and as your own citation states: "BBC still uses this abbreviation [GMT] for patriotic reasons ;-) as a synonym for UTC" (and in Greenwich itself). The other place is in maritime usage where GMT is also a synonym for UTC. And of course, UTC did not exist before 1972 thus GMT is the only correct term to use in the history section. I've change the two true errors in the "List" explanation. — User:Joe Kress 06:42, May 4, 2005 (UTC)
You're right. Re-reading the article, it does make the difference clear. Thanks for looking at this, though. I'm sorry about my confusion. -- User:Wmarkham 02:36, 5 May 2005 (UTC)

::''Time Zone (computer game) is also a historical computer game.'' ::''There is also an Australian franchise of video arcades called Timezone (video arcades).'' Time zones are areas of the Earth that have adopted the same standard time, usually referred to as the local time. Formerly, people used local solar time (originally apparent and then mean solar time), resulting in time differing slightly from town to town. As telecommunications improved and with the expansion of the Rail transport this became increasingly awkward. Time zones partially rectified the problem by setting the clocks of a region to the same mean solar time. Time zones are generally centered on Meridian (geography)s of a longitude that is a multiple of 15 thus making neighboring time zones one hour apart. However, the one hour separation is not universal and, as the map below shows, the shapes of time zones can be quite irregular because they usually follow the boundaries of states, countries or other administrative areas. All time zones are defined relative to Coordinated Universal Time (UTC). The reference point for Time Zones is the Prime Meridian (longitude 0) which passes through the Royal Greenwich Observatory in Greenwich, London, United Kingdom [http://greenwichmeantime.com/]. For this reason the term Greenwich Mean Time (GMT) is still often used (by the BBC, for example, amongst others) to denote the "base time" to which all other time zones are relative. UTC is, nevertheless, the official term for today's atomically measured time as distinct from time determined by astronomical observation as formerly carried out at Greenwich. GMT (UTC) is, incidentally, local time at Greenwich itself only between 01:00 UTC on the last Sunday in October and 01:00 UTC on the last Sunday in March. For the remainder of the year local time is UTC + 1—known in the United Kingdom as British Summer Time (BST). The time for a location is given relative to UTC. Some examples: *Los Angeles, California, California, United States: UTC − 8 (e.g. if it is 12:00 UTC, then it is 04:00 in Los Angeles) *Toronto, Ontario, Ontario, Canada: UTC − 5 (e.g. if it is 11:00 UTC, then it is 06:00 in Toronto) *Stockholm, Sweden: UTC + 1 (e.g. if it is 12:00 UTC, then it is 13:00 in Stockholm) *Istanbul, Turkey: UTC + 2 (e.g. if it is 03:00 UTC, then it is 05:00 in Istanbul) *Mumbai, India: UTC + 5.5 (e.g. if it is 13:00 UTC, then it is 18:30 in Mumbai) *Tokyo, Japan: UTC + 9 (e.g. if it is 11:00 UTC, then it is 20:00 in Tokyo) Where the adjustment for time zones results in a time the other side of midnight from UTC, then the date at the location is one day later or earlier. Some examples: *Cairo, Egypt: UTC + 2 (e.g. if it is 23:00 UTC on Monday 15 March, then the time in Cairo is 01:00, Tuesday 16 March) *Auckland, New Zealand: UTC + 12 (e.g. if it is 21:00 UTC on Wednesday 30 June, then the time in Auckland is 09:00, Thursday 1 July) *New York, United States: UTC − 5 (e.g. if it is 02:00 UTC on Tuesday, then the time in NY is 21:00 on Monday) *Honolulu, Hawaii, USA: UTC − 10 (e.g. if it is 06:00 UTC on Monday 1 May, then the time in Honolulu is 20:00, Sunday 30 April) Note: The time zone adjustment for a specific location may vary due to the use of daylight saving time. *e.g. New Zealand which is usually UTC + 12, observes a one-hour daylight saving time adjustment during the southern hemisphere summer resulting in a local time of UTC + 13! See also: Sidereal time Calculating local time ==History== The first time zone in the world was established by British railways on December 1, 1847—Greenwich Mean Time (GMT) being hand carried on chronometers. About August 23, 1852, time signals were first transmitted by telegraph from the Royal Greenwich Observatory. Even though 98% of the Great Britain's public clocks were using GMT by 1855, it was not made Britain's legal time until August 2, 1880. This paragraph only applies to the island of Great Britain, not to the island of Ireland. On November 2, 1868, New Zealand officially adopted a standard time to be observed nationally, and was perhaps the first country to do so. It was based on the longitude 172 30' East of Greenwich, that is 11 hours 30 minutes ahead of Greenwich Mean Time. This standard was known as New Zealand Mean Time. Multiple time zones were first proposed by Charles F. Dowd about 1863 for American railroads as a teacher to his students. In 1870, after consulting railroad officials in 1869, he proposed four ideal time zones, the first centered on Washington, DC, but by 1872 the first was centered 75W of Greenwich with geographic borders. American and Canadian railroads implemented their own version on Sunday, November 18, 1883, when each railroad station clock was either advanced or delayed as noon, standard time, was reached within each time zone, east to west. The zones were named Intercolonial, Eastern, Central, Mountain, and Pacific. Within one year, 85% of all cities having populations over 10,000, about 200 cities, were using standard time. A notable exception was Detroit, Michigan, which kept local time until 1900, then vacillated between Central Standard Time, local mean time, and Eastern Standard Time until it settled on EST by ordinance May 1915, ratified by popular vote August 1916. This hodgepodge was made uniform when Standard zone time was made legal by the Congress of the United States in 1918. Time zones were first proposed for the entire world by Canada's Sir Sandford Fleming in 1876 as an appendage to the single 24-hour clock he proposed for the entire world (located at the center of the Earth and not linked to any surface meridian!). In 1879 he specified that his universal day would begin at the anti-meridian of Greenwich (now called 180), while conceding that hourly time zones might have some limited local use. He continued to advocate his system at subsequent international conferences. In October 1884 the International Meridian Conference did not adopt his time zones because they were not within its purview. The conference did adopt a universal day of 24 hours beginning at Greenwich midnight, but specified that it "shall not interfere with the use of local or standard time where desirable." Nevertheless, most major countries had adopted hourly time zones by 1929. Even today, they have not been fully realized, with several time zones keeping a standard time that is not offset by a number of whole hours from Greenwich Mean Time. Before 1920, all ships kept local apparent time on the high seas by setting their clocks at night or at the morning sight so that, given the ship's speed and direction, it would be 12 o'clock when the Sun crossed the ship's meridian (12 o'clock = local apparent noon). During 1917, at the Anglo-French Conference on Time-keeping at Sea, it was recommended that all ships, both military and civilian, should adopt hourly standard time zones on the high seas. Whenever a ship was within the territorial waters of any nation it would use that nation's standard time. The captain was permitted to change his ship's clocks at a time of his choice following his ship's entry into another time zone—he often chose midnight. These zones were adopted by all major fleets between 1920 and 1925 but not by many independent merchant ships until World War II. Time on ship's clocks and in a ship's log had to be stated along with a "zone description", which was the number of hours that was to be added to zone time to obtain GMT, hence zero in the Greenwich time zone, and negative numbers from −1 to −12 for time zones to the east and positive numbers from +1 to +12 to the west (hours, minutes, and seconds for nations without an hourly offset). These signs are opposite to those given below because ships must obtain GMT from zone time, not zone time from GMT. All zones were pole-to-pole staves 15 wide except for −12 and +12, which were each 7.5 wide separated by a longitude of 180. Unlike the zig-zagging land-based International Date Line, the nautical International Date Line follows 180 except where it is interrupted by territorial waters and the lands they border, including islands. About 1950, a letter suffix was added to the zone description, assigning Z to the zero zone, and A-M (except J) to the east and N-Y to the west (J may be assigned to local time in non-nautical applications). These were to be vocalized using a NATO phonetic alphabet which included Zulu for GMT. These nautical letters have been added to some time zone maps, like the map of [http://aa.usno.navy.mil/faq/docs/world_tzones.html Standard Time Zones] by Her Majesty's Nautical Almanac Office (NAO), which extended the letters by adding an asterisk (*) or dagger (typography) (†) for areas that do not use a nautical time zone, and a double dagger (‡) for areas that do not have a legal standard time (Greenland's ice sheet and all of Antarctica—Britain specifies UTC − 3 for the Antarctic Peninsula, but no other country recognizes that). They conveniently ignore any zone that does not have an hour or half-hour offset, so a double dagger (‡) has been co-opted for these zones below. In maritime usage, GMT retains its historical meaning of UT1, the mean ''solar'' time at Greenwich. UTC, ''atomic'' time at Greenwich, is too inaccurate, differing by as much as 0.9 s from UT1, creating an error of 0.4 km in longitude at the equator. However, DUT can be added to UTC to correct it to within 50 ms of UT1, reducing the error to only 20 m. == List of time zones and contained areas == Regions marked with asterisks (* or **) observe Daylight Saving Time: add 1 hour in summer (* for Northern Hemisphere summer; ** for Southern Hemisphere). Some zones north-south of each other in the mid Pacific differ by 24 hours in time: they have the same time of the day but differ by a full day. The two extreme time zones on Earth (both in the mid Pacific) differ by 26 hours. A particular day starts earlier in countries with a more positive UTC offset. Thus the first occurrence of a date will be in UTC + 14 and the last of the same date in UTC − 12 (at sea). This gives the interesting feature that during one hour each day there are three different dates in use on land around the world, at 10:30 UTC Monday it is already 00:30 Tuesday in the Line Islands (UTC + 14) while the time is 23:30 Sunday in Samoa (UTC − 11) [http://www.timeanddate.com/worldclock/full.html?sort=2]. Stations in Antarctica generally keep the time of their supply bases, thus both the Amundsen-Scott South Pole Station (U.S.) and McMurdo Station (U.S.) use New Zealand time (UTC + 12 southern winter, UTC + 13 southern summer). Time zone abbreviations are almost always customary, not legal—those listed here only exist in English and are somewhat arbitrary. English time zone names below generally only apply to English speaking areas. The CIA and NAO disagree on the time kept by some Russian oblasts, so both are given below—this may be due to a recent time zone change. === UTC − 12 Y=== Only ships at sea within 7.5 east of 180.

Time zone
Please delet the "The Time around the World" link. Some times there are wrong. In Paris is a winter/summer time. The page doesn't know that. So the time on the page if one hour to early (Sorry for my bad English) --------------------- So brazil adds an hour (daylight savings time) during whose summer? Dec/Jan summer, or the Northern hemisphere's summer?
~ender 2003-09-12 06:53:MST :Brazil adds an hour only in the southern portions of its time zones during the southern hemisphere summer--no DST in the equatorial regions. -- User:Joe Kress 06:06, 2004 Apr 20 (UTC) So, uh, Spain has both UTC and UTC+1 time? At the same time, no less. How's that? ~Marnevel Is Argentina UTC-4 (text) or UTC-3 (map)? User:Psb777 00:56, 3 Mar 2004 (UTC) :Both of these points were corrected by someone. -- User:Joe Kress 06:06, 2004 Apr 20 (UTC) Not all parts of Brazil incorporate summer time. For the most part, only the southern part of Brazil observes summer time. Some towns will however incorporate summer time if there is an energy shortage. But the closer you get to the equator and the further you get into the Amazon, the fewer the towns that use summer time. Additionally, the dates from when summer time starts to when it ends can change from year to year. Each year the government will determine when and if summer time will be used. Summer time can begin anywhere from the beginning of October to the beginning of November. Summer time can end anywhere from early February to early March. As for Argentenia, is UTC -3 hours and summer time (daylight saving time) is not currently used. User:ganteng ==What about Universal Time Zones?== Someone smarter than me needs to incorporate elements from [http://www.virtualtravelog.net/entries/000031.html this article] about the difference between Universal time zones and Local Civil time zones. And are things like "MSK - Moscow Time Zone" an internationally recognized designation? Saudi Arabia is in that zone, but I doubt they discuss Moscow much. User:Mackerm 22:30, 25 Mar 2004 (UTC) :The referenced article has several errors, the major being that there is no international treaty concerning time zones. These 15 'International Time Zones' were proposed by Fleming, but were assigned these letters only after WWII (Fleming used a different letter system). They may be applicable somewhere, like on the high seas and over radio--they do not legally exist over land (I even have my doubts about the 'military' explanation). Rather, each country specifies its own time zones as it sees fit. Many (most?) time zone abbreviations are customary, not legal. For example, EST, EDT, etc. in the United States are customary only--only full words appear in the US time zone law: [http://www4.law.cornell.edu/uscode/15/ch6schIX.html U.S. Law 15USC260-267]
User:Joe Kress 06:06, 2004 Apr 20 (UTC) ::Thanks for the U.S. law. It prompts another question which has been bothering me about this page: Some of the zones include the word "Zone" in their names, and some don't, e.g., "Bering Standard Time" vs. "Hawaii-Aleutian Standard Time Zone". In examining the U.S. code, I never saw the words "Eastern Standard Time Zone". But since multiple countries on a longitude can pick their own names, it seems a losing battle anyway. User:Mackerm 07:15, 21 Apr 2004 (UTC) :::The zone codes (such as "ZULU") are most assuredly of military origin - I used them all the time in the service. In communications the message is always dated by ZULU/UTC/GMT, and local time was often referred to when documenting events using the local zone code (i.e. "ROMEO" or "UNIFORM" for the U.S. West Coast). These zone codes are standardized throughout the U.S. military, and are part of NATO standardization. :The military may or may not have assigned letters (like Z, R, and U) to the time zones. But I am certain that their pronunciation (like ZULU, ROMEO, and UNIFORM) was NOT developed by any military — the International Civil Aviation Organization (ICAO) developed it between 1947 and 1956. Military aircraft and radio have to use it because their countries are members of the ICAO (and the International Telecommunication Union ITU). NATO had nothing whatsoever to do with 'standardizing' the alphabet, because it does not appear in any NATO publication, and I have looked through many NATO publications trying to find it. If you know of such a NATO publication, please reveal its title. For a more detailed history see the NATO phonetic alphabet. Please sign your contribution in some way. — User:Joe Kress 08:15, Apr 14, 2005 (UTC) ==GMT/UTC== This says that UTC is the official term. Official according to whom? In the UK the official term is GMT I think. User:Mark Richards 22:42, 22 Jun 2004 (UTC) : Actually, GMT is not exactly equal to UTC. You can get some information about that at e.g. http://sts.sunyit.edu/timetech/gmt-utc.html, or in the Greenwich Mean Time article. --User:Mormegil 11:02, 11 Jul 2004 (UTC) == land Islands == Can anybody provide the time zone information for the land Islands? Sweden is UTC+1, Finland is UTC+2. So neither would be a safe bet, I think. Marian Steinbach, 17:15, 17 Aug 2004 (UTC) :The land Islands both belong to Finland and are in the Finnish time zone (UTC+2). The CIA map at the beginning of the article would show their time zone as brown (UTC+2), not green (UTC+1), if it were properly downloaded as a pdf file. A suitable source is [http://www.lib.utexas.edu/maps/world_maps/world_time_ref802649_1999.pdf Standard Time Zones of the World] from the University of Texas library (806KB). A magnification of at least 800X is needed. User:Joe Kress 02:04, Aug 24, 2004 (UTC) ::During standard time, land is UTC + 2 hours. During daylight saving time (summer time), land is UTC +3 hours. It might be easier to find information about land Island if you do searches for the capital city of the region which is Mariehamn (sometimes spelled as Maarianhamina). User:ganteng == List of time zones and contained areas == I find the method of listing parts of countries (for example spain/Canary Islands) misleading. It is not clear (until you look through all other zones) that there is more than one entry. Someone unfamiliar with the topic could assume it's Spain and Canary Islands that are in UTC zone, not just the Canary Islands as part of Spain. Unfortunately I currently have no good idea on how to remedy this effectively. --User:Deelkar 14:21, 30 Sep 2004 (UTC) So, uh, Spain has both UTC and UTC+1 time? At the same time, no less. How's that? ~Marnevel Spain has two different hours because the Canary Islands are always one hour earlier -- they are too far off to the West to have the same time zone as mainland Spain. : I think one could use bolded
