About Time: What time zones are used in Antarctica?

Theoretically, the world should be divided into 24 equal time zones, in which each zone differs from the last by one hour. But as the years have passed, the world has turned into a much more complicated place.

Time zones are now much more irregular and sometimes seem positively eccentric, affected as they are by political, geographical and social changes in the real world.

Add to that arguments over daylight saving, and you have a subject that has been the cause of furious debate around the world.

Antarctica is at the bottom of the globe and theoretically at the point where all the time zones meet. So how do they people working their decide what time to use?

Tamsin Gray, British Antarctic Survey meteorologist at the Rothera base in Antarctica, explains.
