From what we have seen, sometimes a refclock can just on insane for a

If you are really concerned, use different brands of unit that get time from
different sources.
This is _really_ good advice.
Of all my refclocks, only the now discontinued Motorola Oncore UT+ has
never given insane timestamps. All my various 'black box' rackmount
servers (3 different models from two different vendors) have failed
once, usually doing something like claiming the date was 2036.
Currently I have a bunch of the last-generation Oncore, one old Oncore,
one Garmin GPS18LVC (which hasn't failed so far, but I've had it less
than a year), one radioclock (DFC77, installed in Germany), and finally
an Endrun Technology cellphone-based unit in Tampa, FL.
