I'm not a hugely experienced user, so I could be way off the
mark here, but this reminded me of a problem we had at home
a short while ago with a new machine:
Basically ntp was setting the time correctly, but the drift was
far too large for it to keep up with (over 1 second per minute
in our case). In order to solve this, we had to use the adjtimex
utility to configure the kernel to expect the actual rate that our
system clock was advancing, rather than the default. ( Apparently this
is because the master crystal is often uncalibrated, so the clock
was advancing at the wrong rate.)
After doing this ntp was able to catch up (although adjtimex had
to be set to run on every boot, as the change is not permanent).
Obviously if it's not a new box I'm seriously far off the mark ;)

Steph
