Sure, UNIX has creation time. Every element on a standard UNIX
filesystem has three times: creation, modification, and access.

What I mean is, you can have a rule that updates the mod time on files
in the same way as directories.
In general it's not a good idea to have directories be prerequisites of
"normal" (non-.PHONY) targets. Only in special circumstances is it
warranted.
