Yes, correct.
JACK-transport timecode (as returned by
jack_transport_query())
increases in steps of the period size. It depends on the application
what to make with this.
Yes, exactly, see below.
jack_frame_time() OTOH estimates the time and includes
the offset
jack_frames_since_cycle_start(); but I don't know how accurate this is.
Yeah, I
think it's best to work with jack frames as returned by
jack_transport_query().
Where does the SMPTE come into play? MTC?
Yes,
I'm writing a jack transport to MTC converter for syncing some
things. It's embarrassingly infantile code at the moment, but I'm
working on it, it's also my first jack program. It displays SMPTE
time in a console at the moment.

I know there's MTC code in xjadeo (and qtractor or some other DAWs, I
think), but I want a standalone console tool. Admittedly, I haven't
looked at xjadeo code in detail, I'm trying to wrap my head around the
concepts first.
Thanks.
