This error showed up in my postfix logs:

May 13 18:07:00 li5-33 postfix/cleanup[14803]: warning: file system clock is 1 seconds ahead of local clock
May 13 18:07:00 li5-33 postfix/cleanup[14803]: warning: resetting file time stamps - this hurts performance

Googling for it revealed nothing useful except some postfix source code, but the source is greek to me.

Anyone have any ideas? I'm on host22.

Cheers,

I think I would try to use ntpdate to sync system first and rerun Postfix to see if this would help.

I wouldn't recommend running ntp on your linode... your host's clock is already running ntp, so your time should always be correct. Here's a forum post regarding ntp.

I found this message on the postfix mailing list:

So, if you're running ntp on your linode, this could be the cause of your postfix problem.

Interesting post on the postfix mailing list. Very similar situation, except that I am not running ntp on my linode.

[root@li5-33 log]# ps -ef | grep ntp | grep -v grep
[root@li5-33 log]#

Any other ideas? I got the same error messages on May 24th:

May 24 21:16:31 li5-33 postfix/cleanup[17025]: warning: file system clock is 1 seconds ahead of local clock
May 24 21:16:31 li5-33 postfix/cleanup[17025]: warning: resetting file time stamps - this hurts performance

This happens very rarely it seems -- only twice in my grep of the logs over the last month -- once on May 13th and then again on the 24th.
