Antarctica is a land of extremes, and its timekeeping is one of the most confusing geographical aspects. Because all lines of longitude converge at the poles, the South Pole technically sits in all time zones simultaneously. This makes defining a 'local time' difficult. In practice, research stations in Antarctica usually adopt the time zone of the country that owns them or the country that supplies them. For example, the Amundsen-Scott South Pole Station uses New Zealand time (UTC+12) because its flights originate from Christchurch. This means you could walk through every time zone on Earth in a matter of seconds by walking in a small circle around the South Pole marker.
