Since there are no boundries in the polar regions � the Arctic is ocean and the continent of Antarctica has no nations - time zone lines follow longitude lines in these places.
Since all longitude lines come together at the poles, you can walk through all of the time zones in seconds by walking around the pole that marks the South Pole. Imagine walking around the pole in the photo above on this page.
There's no North Pole pole since drifting sea ice covers the location and anything put there, such as an automated weather station, drifts away. Our story about the Christmas Day North Pole temperature has more on this.
As a practical matter, having all of the time zones means there is really no time zone for the polar regions. In Antarctica, the U.S. stations uses New Zealand time because most Americans who go to Antarctica for the U.S. Antarctic Program fly to and from there via Christchurch.
Once you arrive in New Zealand for the U.S. Antarctic Program, you could fly to Antarctica, everywhere that a U.S. airplane could take you on the continent, and back to Christchurch without ever having to change the time on your watch.
Since the only station at the South Pole is the U.S. station, the time used there is New Zealand time.
Other nations tend to use their home time zones in Antarctica, which makes radio and e-mail contacts simpler.
The permanent research stations in the Arctic are in countries, such as the Barrow Science Center in Barrow, Alaska, and these use the local time. When researchers venture out onto the Arctic Ocean ice, they can use any time the wish. But, in most cases it's probably easier to use the time for the institution, such as a university, for whom you are working. (Thanks to Antactic Connection)
