Let's use UTC time, switch to a 24 hour clock, and scrap DST.
Time zones, daylight savings time, and AM/PM are a huge hassle to keep straight and a big waste of time to deal with.
Switching to a 24 hour clock system that operates in one global time zone and never adjusts and hour forward or back would be a gift to us, our children, our children's children, their children, and so on.
