> France and Spain have no business being in CET/GMT+1 at all Technically of course you're correct (and you'd probably need to include the Netherlands, Belgium and Luxembourg in there), but thousands of people drive across those borders every day. Clearly the timezones need to have borders somewhere, but it's probably easier in practical terms to keep the timezones of adjacent countries synchronised wherever possible. It also makes sense of the very late-night culture of Spain when compared to countries further east, because they're probably eating around the same solar time as the other countries. The one I find weirdest is the western hold-out Portugal.
