Hello,
I have a fresh Gentoo server running in another city. Today it had frozen and people on location had to reboot it for me.
When I logged in and ran last I found something strange:
| Code: |
root pts/0 XX Thu Feb 17 18:06 still logged in
reboot system boot 2.6.9-gentoo-r13 Thu Feb 17 18:56 (00:-41)
..
root pts/0 XX Wed Jan 5 19:50 - 20:04 (00:13)
reboot system boot 2.6.9-gentoo-r13 Wed Jan 5 20:49 (03:08)
root vc/1 Thu Jan 6 20:27 - down (-1+00:-43)
reboot system boot 2.6.9-gentoo-r13 Thu Jan 6 21:22 (-1+-1:-38)
root pts/0 Thu Jan 6 18:47 - 18:47 (00:00)
..

Notice the negative times (-41 seconds). It seems the clock is running too fast. At every reboot ntp-client sets it right.
What do you think, can something else cause this strange behaviour?
I doubt this has anything to do with the system freeze though.
(The system is running on Abit IS-10 with an P4 ~3+ GHz)
BR,

If it only does it at boot, then I can see the clock getting off. I think that ntpd is used to make sure it stays current since it reboots seldom...?

The scary thing is that the H/W clock drifts about 1 hour per day. Is this common?

I dunno. My 1 unit server used to just freak out on the date for no reason, but that was some hardware problem. After I emerged and configured ntp-client and ntpd to work, the problem was solved.
