Timezones and time changes in the Antarctica

There are 9 different timezones in the Antarctica. Countries with a large distance from west to east are often devided into two or more timezones to adjust daytimes to the position of the sun. Timezones are always computed relative to UTC, the "Universal Time Coordinated".

In the Antarctica, there is a time difference of up to 15 hours between the east and the west. Like in most parts of the USA, there is a distinction in the Antarctica drawn between standard time and daylight saving time (also called winter time and summer time), but this distinction is not nationwide.

The next clock change in Vostok will be on March 26th, 2023 at 6:00 to daylight saving time. The clocks are then set one hour forward.
