Asked by: Gary Dineen, Ireland

The rotation of the Earth means that time zones are dictated by the lines of longitude connecting the two poles. But at the poles themselves, all these lines converge, meaning that technically the poles are in all the time zones simultaneously.

In practice, polar explorers and scientists simply choose whatever time zone is most convenient. Those working at McMurdo Station (pictured) in Antarctica, for example, have chosen to use New Zealand local time.
