Free run Timecode glitch?

[Overlook]

Can anyone explain why timecode would jump backwards from 9:30:00:00 to zero?

I was recording to tape and camera was set to free run.

Thanks.

I don't know but we had a bizzare incident happen on a 5 camera shoot, all of the cameras were set to free run and synced at the same time and there were a few cameras that were either ahead or behind by a few seconds...it was very odd
