What do you mean by "his" time as opposed to "our" time?
This is exactly what I as referring to in my computer model analogy. There is the programmers time, and there is the degree of freedom in the model called "time". These two times have nothing to do with one another.
Have you evidence that there is a "different time" that could be utilised?
No, becasue I am part of the model. No concept of the programmers "real" time has been incorporated within the model. I am unable to produce evidence. But then, God for me has always been a matter of faith.
If not then I suggest you properly define what you mean since time has definite properties that are observable.
Unless you are well versed in relativity, I would sugget that your "definite properties" are not so definite. And if you are, you will understand that time is just a degree of freedom with an odd signature in the metric. And "time elapsed" or "time experienced" is entirely dependent upon your track through space-time.
As for us living well away from any significant curvature, just try out Pythagoras... seems to work well enough. Try it in the early universe, or close to a neutron star or black hole, and you may be surprised. My evidence is all the evidence for GR amounted so far, and my interpretation of GR is sound in that I used to be trusted to teach it at a highly regarded academic institute.
So your experience of time is wholly dependent upon your local gravitational field (i.e. amount of space-time curavture) AND your velocity wrt a comoving object in the universe (Earth, Sun, Galaxy are all close enough to comoving).
To say that God's time must be the same time as ours, one must assume that God is following the same track through space-time as we are, and he is also located in a similar area of low curvature.
My definition of God does not locate him at any point in space or time. Space and time are model degrees of freedom, and he is the programmer, to return to my analogy.
