Yes, this is literally what I’m proposing.
You do not still end up with the same issues. Somebody booking a ticket for a hotel room to be available at 1300 from a different time zone than said hotel will not arrive at the hotel to learn that the check in time is different from their expectation.
Regarding “the link between the hour of the day and the sun’s position,” I’m asserting that we should recalibrate this expectation based on time zones, rather than changing the clock to some fictitious time based on “noon” always equaling “1200.”
who gets to decide that everyone switches over and what is the new global time?
“Global time” in this context is already decided to be UTC. And no one gets to decide on the switch. This is a dream that will never come to fruition. 😕
