Honestly we should just move to a timezoneless universal time. Places in one part of the world could open at 8:00 and close at 18:00 and somewhere on the other side of the world would open from 20:00 to 6:00. No zone change in travel or scheduling meetings would simplify communications and logistics, and you can also ditch this asinine “saving” concept as you’ll have decoupled when the sun rises from an arbitrary number.
