But if space isn’t quantised then why should time be?
No need to answer; that’s one of those questions where if you can understand the answer you wouldn’t have needed to ask the question in the first place.

given that negative mass is a plausible thing, and given that negative mass objects in motion behave as if they're time reversed, and given that observers moving at (or above) relativistic speeds would witness some causality-breaking effects when observing each other...
If time is an emergent quality of space, and space can be manipulated, I think it's plausible that we could arrange energy and mass in ways that allow for meaningful/useful time reversal.
