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 sloooooow response to your question. Thanks for the
