> Drawtext filter already have timecode you want, and its in all in

Yes, there is a timecode option for the drawtext command, creating a
SMPTE, but using it you have to supply an fixed framerate, which is then
used to produce the SMPTE. This is not the right aprpoach for VFR video.

I consciously used the word timestamp in the subject heading. As there
seems to be confusion about the terminology:

I would like to display the exact time where the frame has to be placed
in the timeline, such that I can calculate the speed of the passenger
car, which ran into an accident.
