To add to the other comment, Nix really strives for true and actual reproducibility. Someone please correct me if I'm wrong, but my understanding is that even in builds it uses fake timestamps to ensure if a timestamp is in the resulting binary it doesn't mess up the hash of it. They really do try to go a step beyond others in the realm of reproducibility it seems.
