So what if you are stationed at a base in Antarctica, right at the very geographic south pole? Your whole body could be straddling every time zone at once.
If you are standing at the north pole, you are standing in 25 official time zones at once. If you are standing at the south pole you are standing in 26 official time zones at once. There are over 50 official time zones in the world. For example India, Afganistan and Iran use time zones offset by 30 minutes from the standard 24 time zones. Some countries like Nepal use a time zone offset by 15 minutes.
