Question

With 87 different time zones around the world, how many time zones would you be in at the same time if you were standing exactly(on) at the south pole?

Hint: Daylight Saving time does not exist in Antarctica.

Additional Information

Some zones north-south of each other in the mid Pacific differ by 24 hours in time: they have the same time of day but differ by a full day. The two extreme time zones on Earth (both in the mid Pacific) differ by 26 hours. A particular day starts earlier in countries with a more positive UTC offset. Thus the first occurrence of a date will be in UTC+14 and the last of the same date in UTC−12. This gives the interesting feature that during one hour each day there are three different dates in use on land around the world, at 10:30 UTC Monday it is already 00:30 Tuesday in the Line Islands (UTC+14) while the time is 23:30 Sunday in Samoa (UTC-11).

All of China (which should span five time zones) uses a single time zone.

Answer: 24 time zones. Every 15 degress it changes by one hour. None of the other time zones affect the South Pole time zones. While visiting, you would most likely use the the same time zone of the research center you would be visiting uses.
