A 7 second variance shouldn't be that much of an issue.

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
● ntpd.service - Network Time Service
    Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled;
vendor preset: disabled)
    Active: inactive (dead)
$ sudo systemctl restart ntpd
$ sudo systemctl status ntpd

    Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled;

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.

But doesn't SL7 use chrony?

$ systemctl status chronyd
● chronyd.service - NTP client/server
Loaded: loaded (/usr/lib/systemd/system/chronyd.service; enabled; vendor preset: enabled)
   Active: active (running) since Wed 2016-03-02 17:43:02 GMT; 6 days ago

   CGroup: /system.slice/chronyd.service
           └─767 /usr/sbin/chronyd
