How would local reversal of time work though? I tried imagining it and I just can't come up with anything that makes sense.

One, you can't just hop into a time machine and watch the world outside reverse itself. The world is huge and it will take an immense amount of energy...if it's even remotely possible, what with all the tiny atoms and energy and stuff.

You can have an isolated system though, and forward and reverse the stuff inside from the outside (now idea how, but it makes sense).

But let's say we have a bit of space where time is going in reverse. If you throw a rock (or yourself) in there, how is it going to interact with the space?
