So much politics going on in this map.
The eternal UK ๐ค Portugal alliance and the awkward space it creates between them.
Spain and Poland are in the same timezones.
The weird corridor created by Belarus.
Ukraine is in a separate tz from Russia, I wonder when that was established
What the hell is going on with the light blue in the east?
It still works. You need to know your correction, but it's just like a computer with a slow clock. UTC doesn't explicitly state it, but it's reference is to a non inertial frame, on the earth's surface. (Rotational effects are far smaller than current clock errors, and transmission time errors)
