Here is a quick plot:
http://phk.freebsd.dk/misc/20160126_gps.svg
The two receivers see the same (number of) satelites, but the jumps
happen at widely different times.
Magnitude around 14 microseconds seems confirmed.
These are both Oncore timing receivers.

Never attribute to malice what can adequately be explained by incompetence.
