hi Miroslav Lichvar, You are correct, "the timestamp checked in the clockcheck code should always be a timestamp of the clock synchronized by phc2sys" In this case, we have connected testUnit to interface A. Interface A is providing clock to testUnit (with ptp4l in BC mode) and time is synchro

hi Richard, In phc2sys code, for default config phc_interval, update_clock is called once in a second based CLOCK_MONOTONIC timer. With sanity_check enabled,  clockcheck_sample is also called.   In clockcheck_sample function, we should depend on CLOCK_MONOTONIC to decide if its getting called mo
