Even besides daylight savings time, timezones exist. England and Spain are on a vertical axis, yet the timezone differs by 1 hour. Cross the border from spain to portugal and time jumps a full hour, so there are people living 100 Meters apart with 1 hour time difference.

Timezones are political and economic statements (and sometimes even religious - https://github.com/eggert/tz/blob/main/africa#L853 ). Things like China being all one timezone or India changing to IST after declaring independence https://en.wikipedia.org/wiki/Time_in_India#After_independen... . An example of an economic change was https://en.wikipedia.org/wiki/International_Date_Line#Easter...

Trying to make sense of them as purely time keeping artifacts is bound to have misunderstandings.

> The Spanish also go to sleep later than their European neighbours. According to Eurostat, Spaniards go to bed, on average, at midnight, compared to Germans at 10pm, the French at 10.30pm and Italians at 11pm.
