But you said that you are running a different kernel (32/64 bit), and so this is one variable to check. > I wonder why the time presented by the testptp program does not fit to the > system time. Here is always a delta of about 35 seconds. This 35 second difference is the current TAI-UTC offset. You should make sure that your PTP clock is initialized with the TAI timescale, if you want to run as a grand master clock. (But this has nothing to do with the time jump that you are seeing.) > I hope that helps to identify the issue. >From what Matt Vick said, it sounds like there is a hardware issue with this card.
