Today's catch on CPAN: Time::Duration I needed to print out human-friendly "seconds left until completion" (i.e. "1 hour and 5 minutes") and figured someone else had done that already. It took me no more than two minutes to find, install and use the module. http://search.cpan.org/author/SBURKE/Time-Duration-1.01/Duration.pm CPAN remains _the_ best example of software reuse that I've ever encountered, all categories (and that's considering that my final paper at university was titled "Organizational aspects of software reuse").

Look for Time::Duration 1.02 in CPAN probably by time you read this. By popular request, I added a new function, concise(). Where ago($thing) might return "53 minutes and 4 seconds ago", concise(ago($thing)) will return "53m4s ago".
