Well, supposedly all our servers are synced with NTP. I know the main
cvs server is, and the git server is, but it goes past the anoncvs
server which is a hub.org server so I don't know for sure there - but
I think it is? So I don't think it's the machines-out-of-sync issue.
Or at least the window for that is *really* small.
