I was referring to {m,c}times of the files being compared themselves.

If by "within archives" you mean "of files within, for example, two zip
archives being compared", that's not what I meant.

I just tested diffoscope 77 and it ignores the different {m,c}times of
two otherwise identical test files. Great!

Now, it would be nice if diffoscope had an option to report these
differences :) I wondered if --fuzzy-threshold could be tweaked to make
diffoscope report them, but it did not for the values of 0, 1, and 400.

If I understood your question correctly, please feel free to close this
bug, or ask me to close it.

I'm sorry for the sloow response to your question. Thanks for the
ping!

As I can't reproduce this and there has been no reply I'm going to
go ahead and close it. Re-open if you can still demonstrate the issue
of course. :)
