[time-nuts] Strange 100ns jumps on Motorola M12+T

Hi,
I've recently measured the 1PPS outputs of three Motorola M12+T GPS
receivers using two HP53131A TICs. Antennas are located next to one another.
Now I notice the one M12+T has changed its time offset by 100ns three times
over the period of 48hrs. The jitter remains the same, only the offset that
changes.
I'm currently having a re-run of the measurement. But, in meanwhile, has
anyone seen this kind of behaviour? A firmware issue perhaps?
Regards,
Stephan.
