What do _you_ want to achieve with removing the date stamps?
You started the thread with:

... which is false. The rest of the thread seems like trying
to change the goal post in order to justify change so that as side
effect we'd fix the problem with determinism that you
claimed exists, but that doesn't actually exist.
I.e., this whole thread feels like the classical XY problem.
What is the actual problem that you're trying to solve?
