As a current sysadmin, amen!

The original querant had emailed me personally and I replied
without thinking to copy the list.  I'd suggested he check
cron, both the crontab (or /etc/cron*/whatever) entry for
qrunner, to see whether it had been deleted, and the cron daemon.
Sometimes after a severe clock-shaking it's useful to 
"killall -HUP crond" to get it moving again.

Of course the prudent sysadmin would reboot at that point,
as crond isn't the only daemon that'll sulk following
a period of temporal chaos.  Postfix is my favorite; short of
reboot, I'll always do a "postfix reload" following a significant
clock jump on a server I can't reboot at that time.
