Intervallometer 0.1s accuracy - like 1.2s interval timelapse or similar?

Hi
What lead me here was search for remote intervallometer with better than integer 1s intervals.

I'd like to make any interval by 1/10 of a second accurate.
When at faster pace, 1s, 2s, 3s intervals - it's rather coarse with 25, 50 or 75 times reality for 25 fps movie.
Like controlling the speed of sky clouds or similar to a tempo and right feel for music.

Having a 100D I am thinking of testing, but if not there already maybe wait for it.
I also have a 80D and thinking timelapse movie feature would be swell to set intervall in 1/10s - could very well be as interger, just that value 23 give 2.3s interval. Same for stills intervallometer built in.

Any comments in this is welcome.
Thanks.

Halfway done (accuracy improved, but still operates in integer increments).
