var sequenceDuration = app.project.activeSequence.end - app.project.activeSequence.zeroPoint;

I know it's commented out, but this produces a negative number. If you want duration, app.project.activeSequence.end divided by 254016000000 seems to work without the zeroPoint.

zeroPoint's ticks appear to be the start timecode in ticks.
