Hello Luigi,
Luigi Rosa, 19.03.2007 (d.m.y):
I have a Dovecot installation on a Fedora 4. With the last update from Dovecot RC10 to Dovecot RC27, the daemon kills itself every night with this error:
Mar 17 05:23:11 mail dovecot: Time just moved backwards by 6 seconds. This might cause a lot of problems, so I'll just kill m yself now.
The error appears just after the night maintenance script executes a ntpdate syncronization
ntpdate is version 4.2.0a@1.1196-r
Well, 6 seconds are little more than a blink in human perspective, even if it is a long time for a computer point of view. Couldn't be possible to add a configuration option to avoid the suicide?
I would not recommend using ntpdate to regularly adjusting the clock. Use ntpd or openntpd instead. Both adjust the time in "slighter" steps than ntpdate does: They work by accelerating or slowing down the system clock so that there won't appear "time jumps" as you mentioned them.
Gruss/Regards, Christian Schmidt
