Feature request: display date/time for "other files" (jb_err_pid in particular)

This might help to understand more quickly what jb_err_pid could be relevant to the issue.
Now I have to view the archive contents in another file viewer to see creation time of each file.

Start by locating the UI that lists archive contents and the handling for “other files,” using the jb_err_pid example and attached screenshot as the entry point. Confirm which file timestamp is available and define the displayed date/time format; done means each listed other file shows its date/time without requiring another viewer.
