I'm pretty sure it has. I always feel jet-lagged in Paris, in a way I never felt in London or Berlin (both closer to their solar noon). Also felt deeply unwell in Bilbao (although the city's so brilliant). The most noticeable thing is that 7am is night time about half the year in Paris (from October to April) when it's at least dusk in London all year long (maybe not in December).

It's pretty clear that Paris is less of a morning-city than London.
