I need to keep the drift under the magic 1000 limit that ntpd kills its
self, but despite setting maxpoll really low I get:

Dec 11 23:58:14 host ntpd[4909]: kernel time discipline status change 41
Dec 11 23:59:17 host ntpd[4909]: kernel time discipline status change 1
Dec 11 23:59:17 host ntpd[4909]: time correction of -1123 seconds exceeds
sanity limit (1000); set clock manually to the correct UTC time.


/etc/ntp.conf:

server time.intranet.pdinc.us maxpoll 7

Ideas? If I cannot get ntpd working, then I will have to resort to a cron *
* * * * rdate -s time.intranet.pdinc.us


I would love to see some clear, accurate guidance from anyone regarding time synchronisation within Linux VMs under VMware. From what I've been able to gather, VMware recommend that you disable any in-guest external synchronisation (ntp, windows time etc) and use vmware-tools to sync the time. For now the approach seems to involve trying random kernel boot options and a lot of reboots until you find something that works.

I'd be happy to have my understanding of this issue clarified!

cheers
