Timeline timecode not accurate

I'm editing a :30 second piece and the timecode is :06 seconds off. So my :30 second piece on the timeline is :24 seconds via the timecode indicator. When I export, it's correct, 30 seconds.

The screen shot shows that the in and out points are set to a duration of :30 seconds indicated correctly on the program monitor, but in the timeline, I have positioned the cursor at ":30 seconds" and you can see that it is 6 seconds past the set out point.
