> Also, you may over-estimate the "natural-ness" of standard time. In most places, standard time is already way off of solar time, and as far as I can tell that's not really bothering anyone.

Yes, Greenwich meantime goes through Spain, but we are an hour ahead of the UK's timezone.

I remember being in Chile years ago, travelling pretty much North to Peru, but there was a two hour time difference. They are in different timezones by one hour, and I think Chile had DST but Peru didn't.
