--dry-run

You probably want to be able to resume time as well as pausing it.

Just wish for a steak knife that makes any steak it's blade touches delicious and nutritious for the holder of the knife.

This is the plot of a short story I published, apart from the genie. I shant tell you what happened, just in case.

Ask for a box of genie’s so you can keep modifying your wish when you find the problems.

Be sure to ask it to put you in another time stream or something. Otherwise going back and forward in time does nothing, as going back also rolls back your memory of the future and going forward is just our normal experience every day. Pausing would be bad, since you would not be able to unpause (as you are paused yourself). But even if it were paused and then resumed after something indeterminate happens, you would not have experienced that pause (nor would anything else in the universe), so it might as well not have happened.

You need to be way more precise with your wording, intent and requirements. And then the genie still screws you over, that's kinda the point of the genie figure in myths.
