Is this a virtual machine guest or bare metal host? Usually offsets
this large are only seen on VM guests that aren't setup properly, and/or
riding atop improperly configured hypervisors. If this is a guest,
configure the underlying host to sync with an NTP pool, enable the ntpd
listener on the host ntpd, and configure the guest ntpd to query the
underlying host. Never sync a guest OS ntpd to anything but the
underlying host. You'll also need to stop ntpd in the guest, run
ntpdate once against your host IP, then start the guest ntpd again.
If this is a bare metal host then you probably have a hardware problem.
In that case your system board will probably need to be replaced.
