List of time zones
From Wikipedia, the free encyclopedia
This is a list of time zones, sorted by time offsets from Coordinated Universal Time (UTC). Countries and regions observing the respective time zones are listed under it. This only gives current offsets. For more detailed and historic info the zones must be divided. One list that does so is the tz database. See list of tz zones.
Regions marked with asterisks (* or **) observe daylight saving time: add one hour in summer (* for Northern Hemisphere summer; ** for Southern Hemisphere). Note, some locations use GMT (Greenwich Mean Time) instead of UTC (Coordinated Universal Time) in the definition of local time. For the purposes of this summary, the distinction is ignored.
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. 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) [1].
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.

Old CIA maps, 1995 and earlier, have Nepal at UTC+5:40, which may be their approximation of Kathmandu's local mean time. See Nepal Time.

- Australia (AWST—Australian Western Standard Time)
- Western Australia (most of state)**
- Western Australia begins a 3-year experiment with usage of Summer (Daylight Saving) time on 3 December 2006. Daylight Saving time will be used from October through March, with the late start in 2006 due to late passage of the relevant legislation. A referendum will be held in the autumn or winter of 2009 to determine whether Daylight Saving time usage will be permanent.
- Western Australia (most of state)**
- Brunei
- People's Republic of China
- Note that the whole of the People's Republic of China has the same time, which makes this time zone exceptionally wide. In the extreme west of China the sun is at its highest at 15:00, in the extreme east at 11:00. It also means that on the short (76 km) frontier with Afghanistan, the official time change is 3 hours and 30 minutes. The two western autonomous regions of China, Xinjiang and Tibet, were in UTC+6 during the Republic era (1912–1949), but were moved to UTC+8 after the founding of the People's Republic of China in 1949. Today, residents of the two autonomous regions do everything 2 hours late. For example, lunch is at 14:00 and business hour ends around 19:00.
- Republic of China (Taiwan)
- In 1895, when Japan took over the Taiwan Island, Taiwan was placed within Japan's Western Standard Time (UTC+8) along with the Yaeyama Islands and Miyako Island (now the southwestern part of Okinawa Prefecture, Japan). However, in 1937, Japan abolished its Western Standard Time so Taiwan then observed Japan Standard Time (UTC+9). Taiwan reverted back to UTC+8 after World War II with intermittent usage of daylight saving time until 1979.

- Kwajalein, Eniwetok, and Bikini atolls in the Marshall Islands used to be on UTC−12. Kwajalein advanced 24 hours to the eastern hemisphere side of the International Date Line by skipping 21 August 1993. Eniwetok and Bikini probably advanced even earlier, when the U.S. military relinquished its control of them. [7]
