Nuclear decay doesn't seem to require any particular movement, yet it's one of the ways we measure time, so you might want to re-think that.

I see time as movement and nothing else. Without movement there is no time.
This is well-studied, so the fact you haven't studied it doesn't make it any less valid and merely indicates you have some catching up to do if you want to understand it. Here's a link you can start with if you want to learn. No motion is required, but the literature on this phenomenon is quite extensive so there's a lot more to read if you want to understand it.

When is the decay watched/studied?
Studying and watching and observing happens presently.
The observer must be present.
Past and future will never appear.....except in stories made of words appearing presently, and they disappear as they appear.
Since a radioactive nuclide decays to its daughter at a rate independent of everything, we can determine a time simply by determining how much of the nuclide has decayed. We will discuss the significance of this time at a later point.
