All time zones converge at the earth's poles.   So for scientists working near either the north or south poles, what time zone do they actually use?  

Another way to say it:  what time/date is it at the location of the north and south poles right now?

How did scientists determine this time/date as the official time to go by at the poles?

At the Amundsen–Scott South Pole Station, they decided to use New Zealand time (UTC +12), because all official travel to the station comes to Antarctica out of Christchurch. 

Since the North Pole is an iceflow in the Arctic Ocean, it does not have a permanent settlement that would require them to figure out a time zone standard to live by.
