But that seems to be a display limitation only. As far as I can see,
computation of the track lenght correctly rounds to multiples of
1/75 before taking the difference and then displaying it using 
timecode frames. So the 'clock object' seems to do its internals
to full precision anyway. That is what makes me wonder why it
doesn't display in the same way.
