Does antimatter have negative entropy? If it doesn't, how do you know it's going back in time?

That is the point, we don't know. We would need to produce actual anti-atoms and see how they behave.

I like the idea of a sub-atomic camera obscura, where the aperture is a "hole" in spacetime, rather than a hole in a wall.

There you go.
Also, if I may add: entropy is (at this stage at least) not exactly a perfect proof of the arrow of time,

If any kind of information (or even matter) could really go back in time, it would go into a parallel reality, a timeline that branched off our own timeline.

A hole in spacetime... You mean, a black hole?
