The Earth’s longitudes meet at the South Pole in Antarctica. This means that, theoretically, any of the world’s time zones could be used there. As Antarctica is largely uninhabited, the continent is not officially divided into time zones. However, there are several research stations, each respecting the local time zone. Some stations use the time zone of the country that operates them, others use the time zone of nearby countries.
Amundsen-Scott and McMurdo stations use New Zealand Standard Time (NZST) and New Zealand Daylight Time (NZDT).
Palmer station is a research station in the United States that uses Chile Summer Time (CLST) because Chile is the nearest country.
Troll station uses Greenwich Mean Time (GMT) and Central European Summer Time (CEST), which are 2 hours away.
