That explains a lot. I had never experienced blips that were this large before.

It also happened the day before but I didn't notice the time. I am comparing the 1PPS from two separate units on a 5370. On the one unit I was logging, there were 2 or three phase excursions of up to +/- 28ns or so at these times. And yet, the 5370 showed nothing out of the ordinary on the plot of the phase difference between the two units. So that tells me that it happened to both GPSDOs.
