One of us is confused. Do you have a scope? I have 2 different programs. Both agree that the arrival time is stable. Attached is a histogram. There is no PPS on the system collecting the data so there is 200 micro-sec peak-peak of noise on the reference clock. But most of that is due to daily temperature swings and I don't have enough data to cover that yet. If you don't find anything, I'll clean up a program so you can run it on your hardware.
