System time hopping in Logs

[OliverN]

Hi there,

we are currently experiencing the following issue on our server running OpenSUSE 11.1 and PLESK 9.30.

The system time is set correctly and syncing via NTP.

All of our logs show some "time hopping issues" (mainly messages and mail.info) - this looks something like this:

-x-x- mail.info -x-x-
Mar 1 12:22:32 h1686676 postfix/smtpd[19011]:
Mar 1 11:22:36 h1686676 postfix/smtpd[17919]:
Mar 1 12:22:37 h1686676 postfix/smtpd[19011]:
Mar 1 12:22:38 h1686676 postfix/smtpd[19011]:
Mar 1 11:22:38 h1686676 postfix/smtpd[17919]:
Mar 1 12:22:38 h1686676 postfix/smtpd[19011]:
Mar 1 12:22:38 h1686676 postfix/smtpd[19011]:
Mar 1 11:22:38 h1686676 postfix/smtpd[17919]:
Mar 1 11:22:38 h1686676 postfix/smtpd[17919]:
Mar 1 12:23:00 h1686676 postfix/smtpd[19011]:
Mar 1 12:23:01 h1686676 postfix/smtpd[19011]:
Mar 1 12:23:01 h1686676 postfix/smtpd[19011]:
Mar 1 12:23:01 h1686676 postfix/smtpd[19011]:
-x-x- mail.info -x-x-

So time is hopping between current time and current time -1, but the systems time is fine (checked that via bash script that logs every second the outrput of `date`).

Those time hops within the logentries occur every few seconds!

Maybe anyone can help as I haven't seen something like that before.
