"Time in Antarctica Antarctica sits on every line of longitude, due to the South Pole being situated near the middle of the continent. Theoretically Antarctica would be located in all time zones; however, areas south of the Antarctic Circle experience extreme day-night cycles near the times of the June and December solstices, making it difficult to determine which time zone would be appropriate. For practical purposes time zones are usually based on territorial claims; however, many stations use the time of the country they are owned by or the time zone of their supply base (e.g. McMurdo Station and Amundsen–Scott"

More recent buildings are raised on stilts so that the snow does not build up against the sides of them. In most places on Earth, local time is determined by longitude, such that the time of day is more-or-less synchronised to the position of the sun in the sky (for example, at midday the sun is roughly at its highest).

Advocates cite the same advantages as normal DST without the problems associated with the twice yearly time shifts. However, many remain unconvinced of the benefits, citing the same problems and the relatively late sunrises, particularly in winter, that year-round DST entails. Russia switched to"
