The timezones in the Antarctica
There are altogether 9 official timezones in the Antarctica, but practically only 10 different times. 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 relatively to UTC, the "Universal Time Coordinated".
In the Antarctica exists 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 distiction is not nationwide. 2 regions put the clocks forward by 1 hour in summer. 9 regions keep the standard time year-round.
The next clock change in Vostok will be on March 28th, 2021 at 6:00 to daylight saving time.Back to overview: Antarctica
