Ditto this. On 6T's and M8T's both.

The 6T's do have an odd issue once in a while, right at the roll over 
limit from +10.whatever nS to -10.whatever nS, sometimes the sawtooth 
value comes in with the wrong sign.

We were playing with the 6T's in a GPSDO, against a good crystal it 
stuck out really well in the graph. A software check in the GPSDO looks 
for this and fixes it. Seemed like it happened about once a week to once 
a month type timeframe.

Have you noticed this in your hardware?
