I find the notion odd that this is even a problem to be solved.

It suggests a level of control way below what I would ordinarily consider required for game development.

I have made maybe around 50 games, and I think the level of control of time has only ever gone up. Starting at move one step when I say, to move a non-integer amount when I say, to (when network stuff comes into play) return to time X and then move forward y amount.
