@Paul, Fons,..: does it use a PLL or simply return the
difference from
clock_gettime() since the beginning of the cycle?
jack_frame_time() reads the current time from Jack's usecs timer,
subtracts the cycle start time estimated by the PLL, converts the
difference to frames, and adds the frame count at the start of the
current cycle (which is jack_last_frame_time()).
IIRC Fons reworked some of jack timing functions not
too long ago when
writing zita-a2j, zita-j2a, but don't know if they also affect the
transport API.
The changes do not modify any part of the API, they add to it.
