I've been away from the FreeBSD lists for ages and am looking
for an update on clock drift management under FreeBSD-3.4R. I
asked this on -questions, but got no answers. Perhaps somebody
here knows the answer.
I have a machine that drifts about 7 seconds a day and I'd like
to tweak something in the kernel to keep it closer to the truth.
The clock gets corrected once a day by ntpdate, but I'd like to
avoid such big adjustments.
In the past I used a sysctl under BSDI's BSD/OS to adjust the
value of `tick', but the whole kern.clockrate struct is marked
as not changeable under FreeBSD.
If anybody can tell me which FM has the answer (or even the
actual answer), I'd be grateful. If your answer includes terms
such as {,x}ntpd, then please don't bother, because that's not
the answer (or even an answer) to this particular question.
Please copy any replies to me as my subscription to the list is
going off with this message and won't be completed for some
time.
