A time offset greater than a fraction of second suggests ntpd really isn't 
time-synced.

Not sure if this is related but I've found that ntpd on SL7 systems dies 
during bootup and require a manual start (using an unchanged ntp.conf). 
This is what I see immediately after doing a fresh boot of a SL7 system:

$ sudo systemctl status ntpd

preset: disabled)

If the mirror masters are running SL7 and ntpd is enabled for time sync, 
somebody may want to verify that ntpd really is running on them.
