Time being a measurement of the rate of change of physical THINGS (current most accurate being vibration frequencies of some isotopes - ‘atomic clock’), means that time is bound to the natural world.
For those things outside the natural world, time is not applicable.
Fun part of that is that time is finite - it had a beginning, and it has an end. There is no change to measure without this.
Mr. GG2 also subscribes to your theory. Especially regarding frequencies. I have to go now as this whole thing is starting to sound like science. 😏
