pos: Yukon Time Zone clocks ahead yet another hour on October 30, 1983 to adopt Alaska Standard Time (the former Yukon Standard Time), effectively changing their standard time zone by two hours. Most of the Aleutian Islands moved from the Bering Time Zone (UTC-11) to the Hawaii-Aleutian Standard Time Zone (UTC-10) (until 1983 known as the Alaska-Hawaii Standard Time Zone). Yukon Time Zone The Yukon Time Zone was a time zone that kept standard time; Yukon Standard Time (YST) was obtained by subtracting nine hours from Coordinated Universal Time (UTC) resulting in UTC−9. Yukon Daylight Time (YDT) when observed was eight hours behind UTC.

As a result, there are European locales that despite lying in an area with a 'physical' UTC time use another time zone (UTC+1 in particular); conversely, there are European areas that use UTC, even though their 'physical' time zone is UTC−1 (e.g., most of Portugal), or UTC−2 (the westernmost part of Iceland). Because the UTC time zone in Europe is 'shifted' to the west, Lowestoft in the United Kingdom at only 1°45'E is the easternmost settlement in Europe in which UTC is applied. Following is

pos: UTC+14:00 UTC+14:00 UTC+14:00 is an identifier for a +14-hour time offset from UTC. This is the earliest time zone on Earth, meaning that areas in this zone are the first to see a new day, and therefore the first to celebrate a New Year. It could also be called the latest time zone on earth, meaning that clocks in this zone show the 'latest' (i.e., most advanced) time of all time zones. UTC+14 stretches as far as 30° east of the 180° longitude line and creates a large fold in the International Date Line around the Pacific nation of Kiribati. "Principal

pos: Time zone Time zone A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time. Most of the time zones on land are offset from Coordinated Universal Time (UTC) by a whole number of hours (UTC−12 to UTC+14), but a few zones are offset by 30 or 45 minutes (e.g. Newfoundland Standard Time is UTC−03:30, Nepal Standard Time is UTC+05:45, and Indian Standard

It is the last to celebrate a New Year, and it is sometimes referred to as the International Date Line West time zone (IDLW). UTC−12 is a nautical time zone comprising the high seas between 180° and 172°30′W longitude, and the time is obtained by subtracting twelve hours from Coordinated Universal Time. Ships using this time are the last to begin each calendar day. A number of inhabited islands lie within the longitudinal limits of this time zone, but none of them keeps the date

Yukon Daylight Time (YDT) when observed was eight hours behind UTC. In 1983 the UTC−9-based time zone was restructured and renamed the Alaska Time Zone. When it was created, the Yukon Time Zone included Yukon, and a small region around Yakutat, Alaska (Alaska had been spread across four different time zones at the time). Yukon, which had adopted Yukon Standard Time in 1900, observed a one-hour advance

pos: Time zone is added directly after the time without a separating space. "Z" is the zone designator for the zero UTC offset. "09:30 UTC" is therefore represented as "09:30Z" or "0930Z". Likewise, "14:45:15 UTC" is written as "14:45:15Z" or "144515Z". UTC time is also known as "Zulu" time, since "Zulu" is a phonetic alphabet code word for the letter "Z". Offsets from UTC are written in the format ±[hh]:[mm], ±[hh] [mm], or ±[hh] (either hours ahead or behind UTC). For example, if the time being described is one hour ahead of UTC (such as the time in Berlin during the winter), the

While it "may" be safe to assume local time when communicating in the same time zone, it is ambiguous when used in communicating across different time zones. Even within a single geographic time zone, some local times will be ambiguous if the region observes daylight saving time. It is usually preferable to indicate a time zone (zone designator) using the standard's notation. If the time is in UTC, add a "Z" directly after the time without a space.

UTC+14 was used as a daylight time before 1982 in the parts of very eastern Russia (Chukotka) that used Anadyr Time. UTC+14:00 UTC+14:00 is an identifier for a +14-hour time offset from UTC.

Time zones were identified by successive letters of the alphabet and the Greenwich time zone was marked by a "Z" as it was the point of origin. The letter also refers to the "zone description" of zero hours, which has been used since 1920 (see time zone history).
