Antarctica Info

Antarctica is a bit of a temporal rebel

it technically sits on every line of longitude, which would mean it occupies all 24 time zones simultaneously.

Because there is no single "official" time for the continent, each research station simply picks a time zone that makes sense for its logistics. Usually, they follow the time of their home country or the supply hub they fly in from. +1

Commonly Used Time Zones

Since it is currently February (the Antarctic summer), several stations are observing Daylight Saving Time to match their home bases.

Station	Time Offset	Why?
McMurdo Station	UTC +13	Follows New Zealand (supply hub).
[1] Amundsen-Scott (South Pole)	UTC +13	Matches McMurdo for flight coordination.
Palmer Station	UTC -3	Follows Chile (supply hub).
Rothera Station	UTC -3	Follows the port of Ushuaia, Argentina.
Casey Station	UTC +8 / +11	Follows Western/Eastern Australia seasonal changes.
Vostok Station	UTC +6	Follows Russia (Omsk Time).
Troll Station	UTC +0	Follows Norway (Greenwich Mean Time).

In our International Information list, Antarctica's business region is categorised as "None." This is because the Antarctic Treaty prohibits any country from owning the land or conducting sovereign business there.

If you were forced to pick one for a logistics database, most companies treat it as APAC (because of the New Zealand/Australia links) or AME (due to the South American jumping-off points), but "None" is the most legally accurate!
