I hope the EU will follow soon. Or at least my home country. Since the EU already has different time zones, the stalling because "all should have the same time" doesn't make sense.

I wouldn't mind either. But I do see the point of different countries wanting to be in different time zones. I live in Berlin. My parents are in the Netherlands. We're in the same timezone but there's a good 30-40 minute difference between when we have our sunrise and sunset. Very noticeable when you do a video call around that time. I'll be sitting in the dark and it's still light on their side. The central European timezone spans from Spain in the west to Poland in the East. that's roughly 9 degrees west longitude to 24 east. A normal timezone should be about 15 degrees (360/24), not 33. That's more than two hours difference between when the sun sets/rises from east to west.

So, I can see that how some countries like Spain and Poland might want to make different choices when it comes to losing or keeping the hour permanently as Spain is basically in the wrong timezone. If you want to have noon occur when the sun is highest in the sky, you need to be close to 15 degrees east (roughly the Polish border with Germany).

Much of Spain is technically west of Greenwich (0 degrees longitude). Which means it should be GMT. You could make the same argument about France and the Netherlands being closer to Greenwich than the Polish border with Germany. I'm at 13 degrees east in Berlin, so pretty close.

Countries further north tend to care less about this because most of the year it's either too dark or too light most of the time. I used to live in Sweden and Finland. Daylight saving doesn't do anything useful there. There's not much to save when sunrise is just before noon in the winter and shortly after midnight in the summer. In Helsinki (not in the same timezone), the sun is already rising around 2am in the summer and it's still dark at 10am in the winter.
