That's interesting. Can you post your `ntpq -p` output here? For me
the problem is not just the inaccuracy without ntpd. When ntpd is
running, its polling interval stays very low (around 64 seconds)
because it keeps having to reset the clock. My message log is filled
with the following:

Nov 17 03:59:35 ntpd[568]: time reset +1.684038 s
Nov 17 04:18:44 ntpd[568]: time reset +1.840754 s
Nov 17 04:37:33 ntpd[568]: time reset +1.581726 s
Nov 17 04:57:28 ntpd[568]: time reset +2.078004 s
Nov 17 05:16:48 ntpd[568]: time reset +1.558386 s
Nov 17 05:36:41 ntpd[568]: time reset +2.245156 s
Nov 17 05:56:07 ntpd[568]: time reset +1.486516 s
Nov 17 06:23:25 ntpd[568]: time reset +2.386411 s
Nov 17 06:59:47 ntpd[568]: time reset +3.175640 s
Nov 17 07:19:02 ntpd[568]: time reset +1.134997 s
Nov 17 07:38:01 ntpd[568]: time reset +1.499600 s

And so on... Could it be a problem with the hardware on host machine?
I use the same ntp.conf file on several FreeBSD 7.1 servers, and the
VPS is the only one that has this problem. Actually, that's another
thing - I upgraded my VPS to 7.1 a few months ago, but I don't
remember if I had this problem when using 7.0. Anyone know if there
were changes made to 7.1 that would make the OS behave differently
under Xen?
