NM vs clock

[Neal Becker <ndbecker2 gmail com>]

I have a virtual machine running F12, setup to bring up eth0 at boot (nm 
controlled).

It kept failing dhcp.

Notice the clock changed from 04:00 to 09:00 when ntpd started.  Apparantly, 
confusion over the clock time.

Fixing the clock time seems to have solved the problem.  I guess the time 
change made dhclient think it should have timed out?
