[wlug] NTP syncing on a local network

I'm wanting to sync two machines to within 1 msec for my research using ntp. Questions: - is this realistic given how clocks drift? Has anybody done this? - is there a quick way to force them to converge I've had a quick read of the ntp pages and made one of my machines a broadcast server and the other broadcast clients I think but they seem to be taking a while to converge. The man pages say they will fix at 0.5ms/sec but I'm not seeing that. Comments appreciated. NB I don't want my clocks to be deadly accurate to the "real world", just to each other.
