[mythtv-users] NTP drift...

I'm sure the NTP mavens will come out of the woodwork to correct
me, but I would check a few things:
- Could you send the output of "ntpq -p" so that others can see that
it's sane?
- Does the ntp drift file have a reasonable value?
If its value is maxed out at +/- 500 ppm, that can keep your
system converging even if it makes big step corrections several
times a day.
A high value (say, over +/- 200 ppm) may indicate hardware problems
of some kind. Sometimes it just means that NTP got confused because
of weird conditions. Removing ntp.drift and restarting the daemon
may get it retrained to a good range.
- Is /var/log/messages recording anything from the ntpd process?
