Time in Antarctica

Time zones in Antarctica

Antarctica sits on every line of longitude because the South Pole is on the continent. Theoretically, Antarctica would be located in all time zones; however, areas south of the Antarctic Circle experience extreme day-night cycles near the times of the June and December solstices, making it difficult to determine which time zone would be appropriate. For practical purposes time zones are usually based on territorial claims; however, the time zone of their supply base is often utilised. In most areas south of 80 degrees latitude, Coordinated Universal Time is assumed despite the limited presence of clocks.
