what just happened (time went backwards?)

[Neal Becker]

This f20 server has been running just fine for months.  Today it became 
unresponsive.  Couldn't ssh into it (ping ok).  Not thrashing disk (disk light 
not continuously on).

I hit the power button and rebooted.  After reboot, checked /var/log/messages:
