Having lived in all 3 countries, I can tell you that Austrians (roughly centred on solar time, and Vienna, 1/4 of the country's population in one city, almost half an hour ahead of solar) are very much early risers compared to Spaniards. (the eastern part of Spain is almost 1 hour behind solar, most of the country even more so) Opening times of shops reflect that; it's not unusual for supermarkets in Spain to open at 9:00, while in Austria 7:30 is probably the most common. The evening meal is generally also consumed much later (clock time) in Spain. The UK is somewhere in between, which again fits with the solar time offset.

Drawing any conclusions beyond that is frought with the peril of confounding factors…

Indeed: I once walked into a restaurant in Spain and was told they were not yet open for dinner. The time was 8 pm.
