Bit of a thought experiment here.

Say you were conducting some procedure on a lab bench, and you wanted to record the whole thing to prove it to someone else. So you decide to film the entire thing with a fixed camera. It doesn't mater what the procedure is, it might be something to present to a jury, it might be something to prove an invention to a sceptical audience - but you want to make absolutely sure there is no way the video was edited, and that video recording is the whole thing uninterrupted from start to finish.

What objects could you place on the bench to prove the date, time, and the uninterrupted sequence of filming?

I was thinking a newspaper for starters - that confirms the no earlier than date, but not some later edit using a copy of an old newspaper.

I'm having trouble thinking of something to prove the time of day - a clock can be set to any hour later, and something to prove an uninterrupted sequence - needs to be something random that can't be stopped and reset, but I can't think of what.

Any ideas?
