Although Randal L. Schwartz posted a hillarious comment on Date::Manip
(http://archive.develooper.com/beginners%40perl.org/msg22416.html)
you should take a look at that module. I have used it quite a lot to
let people pass more or less generic time/date specifications to my
scripts. It does for example things like that:
---------- snip ----------
nijushiho:~# perl -MDate::Manip -le 'print UnixDate("44 days ago", "%Y%m%d")'
20020313
nijushiho:~#
---------- snip ----------
It comes at a price though, so I wouldn't use it to process some 20 million
lines of webserver logs in a nightly run :-)
