Default Timecode on programme-as-broadcast archive material

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?


You'll notice that there's a clock before 10:00:00:00. If you start
the programme at 00:00:00:00 the clock would run from, say
23:59:30:00, which can be a trifle disconcerting.

10:00:00:00 was the BBC convention for complete programmes, but
inserts could be run from any time code which seemed appropriate.
