The amount of sun is not dictated by what time we arbitrarily call it. People’s scheduled times for work would vary based on location, so someone in CA who currently works 9-5 would would work like 17-3. Which would be the same as the sun coverage locally is concerned.
Yes, other than a 1-time adjustment, it’s no less arbitrary than the current times they use.
They’re right to, it literally causes a rise in deaths, with this that goes entirely away, so yay?
I’m not sure you’d still use am/pm, but yeah. What intrinsic negative is there? Who cares if they have to be at work at the same point relative to the local day/night cycle but it’s named something else.
They also come with the baggage of dst and timezones, part of which you list below.
Yeah, this is all dumb, so why not make all of these oddities go away.
