[LAD] JACK transport timebase and its callback

Hello! I just read through the JACK transport section in the JACK reference again. If you want to be timebase-master you can (or must) supply a callback function to update the time-info. Does my program need audio thread (a process function?) Which timing source is used to update the time? Does my program provide it or does JACK provide it and my program only really kicks in when I want to relocate (jump to another position)? I am correct in assuming, that my code doesn't have to be multithreaded (at least not look multithreaded) if I want to use the JACK transport interface (control and timebase)?
