This is probably a weird, obsessive question...
I've noticed that if you see a programme from a tape archive (eg BBC's
Windmill Road) with burnt-in timecode, the TC often begins at 10:00:00
rather than 00:00:00. An example is

chose to begin the TC at a "zero" of 10:00:00?
Early time code based video tape editors were unable to cue up a tape for
an edit at 00:00:00:00 because a 10 second pre-roll would need to be at
23:59:50:00 which the edit controller would see as 23+ hours into the
tape. In other words it couldn't handle a negative pre-roll, I don't know
if later ones could but of course now it's all non-linear editing they can
