I'm a little irked by time zones being divorced from sun times while time zones in some countries become larger and larger. But it turns out that people solve that for themselves: two cities in the same timezone but >1000 km apart east-west have daily activities diverging by about 1-1.5 hour: different schedules for transport, shops opening and closing times, etc. However, I'm fairly sure the growth of time zones will stop before people aren't able to reference day times with any certainty: ‘4 am’ still means ‘hella early’ worldwide (afaik).
