Where I'd like to end up: a Field Type that allows me to record _and_ tally durations in hours, minutes, seconds (frames optional).
- Make the "Timecode" Field Type eligible for sums under Summaries. However, this would involve a separate feature request: making the timebase user-definable (24, 25, 30fps).
- Create a new Field Type that records hours, minutes, and seconds (no frames), and make it eligible for sums under Summaries. This Field Type would not be tied to dates or a specific fps. This would differ from Duration mainly in scale -- hours, minutes, seconds instead of days, hours. I would call this Field Type TRT (Total Running Time).
In either case, I would not want the hours not to be tied to an arbirary 24-hour limit or rollover. In other words, 168 hours, 5 minutes, and 11 seconds would be represented as 168:05:11[:00].
