I am looking for an answer based on Logic and not necessarily a technical one.
Suppose, if I have a video clip of me doing something (let's call it event 2: E2) and would like to convincingly prove to others that it happened after a certain date - say, 2011-01-01. One rather simplistic idea would be to do E2 while standing next to a TV show/news showing an event E1 that has happened only once, ever, on 2011-01-02. This would prove that E2 happened after E1 and therefore after 2011-01-01. I know you can completely disprove this idea by faking it using a video older than 2011-01-01 and superimposing a very recent TV shot. For the sake of the problem, assume we can guarantee using some technical solution that the video was not edited since the time it was saved by the camera.
My Question is: Using a similar reasoning, can you prove that a video clip was shot in continuous time (real-time) without recording paused in-between?
For example, if you are standing before a clock, you can pause the camera and the clock, take a break for 5 minutes and then get back to your last pose, resume the recording and clock simultaneously and it would be hard to tell if you had taken a pause in between. So this idea cannot be used to prove the clip is recorded continuously.
Do you have a logical solution for this?
