> Spain is already in the wrong time zone for standard time
That's probably even more of an issue for Spain, made even stranger by the fact that Portugal is in the "correct" timezone.
Yeah, it is even more weird when going from Portugal to Galicia, as the longitude kind of doesn't change.
Even if it was a political decision, as answered on sibling comment, moving east at least makes some sense for the common person.
This is a consequence of WW2, Spain and France moved to CET to align themselves with nazi germany. Portugal and the UK didn't.
