Question

No, Realy, I'm serious.

Answer 1

Time Zones of Antarctica Basic time zone concepts

Rules currently in force

There are other active stations in Antarctica. We don't know what time they observe.


Time zone history

Source: This information was adapted from the tz database. Zone names come from that database. The names don't necessarily match any names used in the "real world".

Find the Zone Name in the table above. Then use this table to find the Rule and Standard Time for the given time and date. Zone Name Rule Standard Time Effective Dates
Antarctica/Casey Standard UTC+8 1969 to present
Antarctica/Davis Standard UTC+7 1957-01-13 to 1964-11, 1969-02 to present
Antarctica/DumontDUrville Standard UTC+10 1947 to 1952-01-14, 1956-11 to present
Antarctica/Mawson Standard UTC+6 1954-02-13 to present
Antarctica/McMurdo NZAQ UTC+12 1956 to present
Antarctica/Palmer ArgAQ UTC-4 1965 to 1969-10-05
ArgAQ UTC-3 1969-10-06 to 1982-05
ChileAQ UTC-4 1982-05 to present
Antarctica/Syowa Standard UTC+3 1957-01-29 to present
Apply the Rule, using the Standard Time for the given time and place. Rule Years Description
Standard All Standard Time with no DST
ArgAQ Standard Time, with DST = Standard Time + 1:00 during the following periods:
1964-10 to 1966-03 from October 15 at 00:00 until March 1 at 00:00
1966-10 to 1967-04 from October 15 at 00:00 until April 1 at 00:00
1967-10 to 1969-04 from the first Sunday in October at 00:00 until the first Sunday in April at 00:00
1974 from January 23 at 00:00 until May 1 at 00:00
1974-10 to 1977-04 from the first Sunday in October at 00:00 until the first Sunday in April at 00:00
ChileAQ Standard Time, with DST = Standard Time + 1:00 during the following periods:
1982-10 to 1998-03 from the second Saturday in October at 24:00 until the second Saturday in March at 24:00
1998-09 to 1999-04 from September 27 at 00:00 until April 4 at 00:00
1999-10 to present from the second Saturday in October at 24:00 until the second Saturday in March at 24:00
NZAQ Standard Time, with DST = Standard Time + 1:00 during the following periods:
1974-11 to 1975-02 from November 3 at 02:00 until February 23 at 02:00
1975-10 to 1989-03 from the last Sunday in October at 02:00 until the first Sunday in March at 02:00
1989-10 to 1990-03 from October 8 at 02:00 until March 18 at 02:00
1990-10 to present from the first Sunday in October at 02:00 until the third Sunday in March at 02:00


Time zone names

Casey, Palmer, and McMurdo observe the standard time of their supply bases, which are in Western Australia, Chile, and New Zealand, respectively. Therefore, they use the same time zone names as those places. Palmer was on Argentine time until 1982-05.
The only names given for the time zones of Davis, Mawson, and Syowa are Davis Time, Mawson Time, and Syowa Time. These names were made up for the tz database. There may be more authentic names, but the tz database hasn't heard of them.
The Dumont-d'Urville time zone was called Port-Martin Time from 1947 to 1952, and Dumont-d'Urville Time from 1956 to the present. Again, these names were made up. The Port-Martin base, 50 km. from Dumont-d'Urville, operated from 1947 to 1952 and then burned down.

Answer 2

Antarctica has no official time zones .

Therefore , researchers in the Arctic and Antarctic regions of the earth usually use the time zone associated with their research stations. For example , since nearly all flights to Antarctica and the South Pole are from New Zealand , New Zealand time is the most commonly used time zone in Antarctica .

Answer 3

Antarctica actually has no official time zone.

Answer 4

but they do have an area code I believe
or is it zip code
