thank you for the input @cnacws!
interestingly enough, I also recently came to realize that time is attached to motion in the physical world. The idea of it being an epiphenomenon makes sense to me.
I made a post about time a few months ago:

Psychological time means the movement of thought. The "time" that it takes for thinking to transpire. Would there be (inner/psychological) time without thinking/thought?
It seems to me that there would only remain the time which you have pointed out: an epiphenomenon of movement in the physical world.
