Video Surveillance Camera Time

Hello,

At work sometimes I have to get video footage from surveillance cameras. A lot of the cameras have the wrong time and I need to figure out how far off the time is on the camera.

My question is does anyone know of an app, website, or something where I could enter the times in and it would tell me the time difference if it is fast or slow and how many minutes or hours?

It just gets tiring trying to figure this out.

Thank you

On the assumption that you know the original time difference (e.g. at the start of the video)

Could you do a formula in Numbers where you enter the time difference and then the time onscreen and it provides the actual time.

I think this might be what you’re looking for.
