Time is the non-spatial fourth dimension along which things travel in only one direction. Even if in the three physical dimensions the process could go in reverse, has it really reversed in time? The history of it breaking and being fixed has persisted, and so now it's not the same glass that it was before. It's now a glass which had been broken but is now fixed. It's a non-material distinction, but time is non-material. And in that way, it hasn't reversed at all.
