That’s a good idea! Instead of discrete timezones, let’s have continuous timezones!
I’ve been a proponent of this for ages. It makes no sense to cross some imaginary line and suddenly time shifts. Time should change constantly as you move east or west, up or down. Everyone has their own personal time, which is constantly updated.
Bonus: no more daylight savings switch.
How do you agree on a meeting time with a group of people who all live in different places of your country?
That was kinda the situation in the past: Every town would have its own time, synced to the local noon every once in a while as the precision of the church or townhall clock demanded. That stuck around until railroad operators and passengers got sick and tired of dealing with the timetables that produces.
