Alternatively, we have this arbitrary standard of 9am means morning, if we share a single universal time, different places would just have a different arbitrary time being the “morning” instead.
Or, we could collectively realize time is but an illusion and transcend this silly problem.
i would aruge that the arbitrary factor of “9am being morning” is entirely to do with the fact that morning is actually a solar time phenomenon, whereas global time does not have the concept of morning, since it is merely imitating the local solar time.
Local solar time being the literal point in the sky that the sun is in.
It gets even funnier if we include people who aren’t “normal” I for one, consider noon to be morning.
We could keep the 0 hour as the “middle” of the night and 12 being the “middle” of the day (though I’m not sure if that’s really the sun’s high spot for the day for any places).
But with fully controlled mirrors, we could make it exactly 12 hours, so we could just then switch to the 0 hour being when the sun comes up.
