* Canonicalise timestamps in the Nix store to 1 (1970-01-01 00:00:01
UTC) rather than 0 (00:00:00). 1 is a better choice because some programs use 0 as a special value. For instance, the Template Toolkit uses a timestamp of 0 to denote the non-existence of a file, so it barfs on files in the Nix store (see template-toolkit-nix-store.patch in Nixpkgs). Similarly, Maya 2008 fails to load script directories with a timestamp of 0 and can't be patched because it's closed source. This will also shut up those "implausibly old time stamp" GNU tar warnings.
