The local clock (as a refclock) is going to be the least accurate
thing you can sync to, unless you're running a Windows machine
connected to a Meinberg GPS device which has a driver to directly
control the system clock (bypassing NTP), in which case you'll be
following their instructions at
As such, if you're going to be using the local clock as a
refclock, you should set the stratum value to a sufficiently high
value that you won't select it as the SYSPEER unless there is
absolutely no other option.
