Why not just run ntpd and be done with it, ensure you start ntpd with "-g" option
If you are responding to me (it is hard to tell when you top post) I am running ntpd. I still have the problem described below. I have never used the -g option but the Red Hat init scripts call ntpdate at startup before ntpd starts. In reading the man pg, it would appear that I should get the same results as using the -g switch, since the -g switch only allows 1 large adjustment of the system time.

Hello,
I am experiencing a number of 'Time moved backwards errors' such as:
Mar 27 11:38:20 host-78-129-239-60 dovecot: imap-login: Time just moved backwards by 729 seconds.

on my Centos 5.2 openvz - based VPS
I have raised the issue with my VPS provider, who are responding that 'the jury is still out' as to whether this is a system, or Dovecot problem.
FWIW I saw this the other day on a real-machine CentOS 5.2 system after a severe crash in which the system put all the drives into read-only mode. The machine had to be power-cycled and dovecot complained the clock was off by 5 minutes. Maybe something else going on with the 2.6.18 kernel? Dunno.
I see this all of the time on an EL4 machine when it is under high load. The clock is synced to ntp but I still get dovecot killing itself. Sometimes ntp looses sync but not always.
I have a cronjob check every 5 minutes to see if dovecot is running and if not restart it. I know that is not the right answer and I hate things like that but until I figure out how to fix it or upgrade the machine (coming soon) I will live with it.
I am just throwing this out in case it means anything to someone else.
FWIW dovecot version == dovecot-1.0.3-14
