Hey Tom, speaking of the Arctic (or more specifically, the Antarctic), you should do a video on what time zones do at their convergence points.,(reply>), I'm not sure about the Arctic, but for the Antarctic they use the timezone of the country which owns the closest station.  I mean, the information is out there, I just thought it'd be a good video for Tom to do.,(reply>), I believe they do the same as on the ISS (where they orbit the Earth 16 times every day, so keeping up with time zones would be a nightmare), which is to stick to UTC.
