clock running too fast

[Thierry Lacoste]

On one of my servers running 6.1-RELEASE-p10 I cannot keep the clok
synchronized using ntpd. AFAICS this is certainly because the clock
is running way too fast (about one second per minute).

After I run ntpdate then ntpd the clock is drifting and /var/db/ntp.drift
contains 0.00.

Is there a way to slow down the system clock (something like tickadj
under some linux distributions) ?

Thierry.
