Date::Manip is a Perl module that contains a set of routines designed to make any common date/time manipulation easy to do. It aims to make operations like comparing two times, calculating a time a given amount of time from another, or parsing international times simpler. . The focus of Date::Manip has been to be able to do ANY desired date or time operation easily, though not necessarily quickly. There are other modules that can do a small subset of these operations quicker, so if speed is a primary issue, you should look elsewhere.
