Since all time zones converge at the South Pole, there is no reason for placing it in any particular time zone. But as a practical convenience, the Amundsen-Scott South Pole Station keeps the time of which country?
South Pole once per year, and all lines of longitude, and hence all time zones, converge. There is no "a priori" reason for placing the South Pole in any particular time zone, but as a matter of practical convenience the Amundsen–Scott South Pole Station keeps New Zealand Time (UTC+12/UTC+13). This is because the US flies its resupply missions ("Operation Deep Freeze") out of McMurdo Station, which is supplied from Christchurch, New Zealand. Due to its exceptionally harsh climate, there are no native resident plants or animals at the South Pole. Remarkably, though, off-course south polar skuas and snow petrels are occasionally seen
Amundsen–Scott South Pole Station The zone identifier in the IANA time zone database is Antarctica/South Pole. Amundsen–Scott South Pole Station The Amundsen–Scott South Pole Station is a United States scientific research station at the South Pole, the southernmost place on the Earth. The station is located on the high plateau of Antarctica at an elevation of 2,835 metres (9,301 feet) above sea level and is administered by the Division of Polar Programs within the National Science Foundation under the United States Antarctic Program (USAP). It is named in honor of Norwegian Roald Amundsen and Englishman Robert F. Scott, who led separate teams that raced
