That's kind of a mess even now, lots of logistical concerns, but with all the technological infrastructure we have, we could kind of do the opposite... Have watches and clocks that are always synced exactly with the day/night cycle no matter where you are. It changes a tremendous amount about how we do so many things, but it's an interesting idea.

I kinda think it might make sense to normalize using both, but at that point it feels like we may be making things worse.
