Hi,

If you do this twice:
7z u -tzip $some_zip $some_path/$some_file
strip-nondeterminism --timestamp $some_zip
and then diffoscope the two results I *expect* them to be
indentical, but I get this for each folder of $some_path:

However, if I pass `-mtc=off` to 7z, all is fine. That
disables "NTFS timestamps for files: Modification time, Creation
time, Last access time". So it seems strip-nondeterminism is not
aware of this timestamp at the moment.
