I think we should also officially adopt yyyy.mm.dd.hh.mm and the 24hr clock. (I forget the official name of that formatting, and I'm on my phone, so I'm lazy.)

And the International Fixed Calendar, too.

Also, metric.

That one's a bit tough since it really only affects people who are working far apart -- at which point you can just agree on what time something is.

For example, it's great to think of noon as being the middle of the day no matter where you are. There are clearly advantages the other way around as well.

DST is just disruptive, though. "Hey everybody! Let's have two ones o'clock this morning!" That created all kinds of confusion in my house last night when things were running at one I didn't expect to be running until two.
