I'd just like to publicly proclaim that I'm an idiot.  I knew that.   
And it wasn't even at 4am, which is my usual excuse.  This after two  
to three weeks of the stupid DST change here in the US.

Absolutely!  It's been standard on Macs for some time (it's how it  
syncs with time.apple.com, etc).  It's just braindead easy for one or  
two machines.  If you have more than that, making one or two machines  
as broadcast/multicast servers and having everything use them is  
straightforward, too.
