TranscriptionA map of the world with vertical lines marking the time zones from UTC-12 to UTC+12. It has a legend:

Wrong Time

"Natural time zones" are 15° in longitude. Land in red observes a time other than the zone it lies within. Smaller islands depict their 12 nautical mile territorial sea, for visual effect. In some cases this includes a state's archipelagic waters.

15 degrees of longitude for a timezone stops making sense that close to the poles

Yeah exactly. The concept of time zones themselves really starts to break down at those latitudes, and I don't think it matters what map projection you show it on (though something like Robinson or Winkel-Tripel, with curved time zones, would definitely make things clearer), it's a fundamental aspect of the way in which light is hitting the Earth's surface.
