With apologies to Douglas Adams… Time is an illusion. Sunset time doubly so.

We already pick arbitrary times for sunset twice a year. Nobody has to move anywhere to pick one arbitrary time for sunset and leave it that way. There’s nothing inherently “correct” about setting the time based on where the sun is positioned in the sky at “noon”, sometimes, from certain arbitrary points of observation.

Sunset isn't arbitrary, Its defined as the time the sun transitions below the horizon of your location. Its time varies based on where you are on earth and where the earth is in relation to the sun, but its not arbitrary.

That’s not what I said was arbitrary. The time we assign to it is arbitrary. It already is arbitrary, there isn’t any “correct” time of day to assign to it at any location. To the extent assigning a time at all serves a particular purpose, it’s a social purpose, and its assignment should be based on that.

Don't like it? Uproot your life and family, potentially switch jobs, leave behind your friends, all so you can solve an artificially-created problem that I have arbitrarily decided is actual and correct!
