I often wish we just dropped time zones, and agreed to use UTC for everything. Or TAI, whichever.

I also think AM / PM suck, and we should drop them in favor of simple negative / positive, relative to UTC.

EDT UTC
12:00a 05:00
6:00a 11:00
9:00a 14:00
12:00p 17:00
3:00p 20:00
6:00p 23:00
9:00p 26:00
12:00a 29:00

Whereas, for example, the same day in South Korea would look like

KST UTC
12:00a -9:00
6:00a -3:00
9:00a 0:00
12:00p 3:00
3:00p 6:00
6:00p 9:00
9:00p 12:00
12:00a 15:00

At least this way, the math is right in front of you. You can clearly see these things barely overlap, just by the numbers.

To see how these things overlap, I’ll merge them

EDT UTC KST
  -9:00 12:00a
  -3:00 6:00a
  0:00 9:00a
  3:00 12:00p
12:00a 5:00  
  6:00 3:00p
  9:00 6:00p
6:00a 11:00  
  12:00 9:00p
9:00a 14:00  
  15:00 12:00a
12:00p 17:00  
3:00p 20:00  
6:00p 23:00  
9:00p 26:00  
12:00a 29:00  

Maybe I just don’t like time zones, but I think it’s better if it’s the same time for everybody. Haters gonna hate.

You run into some aliasing, but that’s hardly an issue so far. Everybody knows what Friday 11p-2a means.
