diffutils: Timestamp Order
18.1.5 Outputting Diffs in Timestamp Order
------------------------------------------
Applying 'patch' to a multiple-file diff can result in files whose
timestamps are out of order. GNU 'patch' has options to restore the
timestamps of the updated files (⇒Patching Timestamps), but
sometimes it is useful to generate a patch that works even if the
recipient does not have GNU patch, or does not use these options. One
way to do this would be to implement a 'diff' option to output diffs in
timestamp order.
