I saw that timer thing? That's what you mean by impact of real-time timer. Anyway, I want a video editing and effects to add the wrong time for what looks like a hidden camera bit, but I do not know how.

If I had to do it frame by frame, it should be time. Who knows, wherever you have a sample or a tutorial that the effect of the timer have made in real time?

And as further consultations as set out in this regard BZZZZZT in 35.56 seconds?
