[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?
