This seems to require me to write a tag for each method I want from
Date::Calc or a wrapper for the entire module, both seem like poor

I'm already using $Tag->time and $Tag->convert_date and they work fine
for most things, however I am doing some reports on shipment volumes
and delivery performance so I need some more sophisticated date
manipulation and comparison routines.

I should have phrased the question like this:

Where do I add "use Date::Calc qw( Days_in_Year Days_in_Month ...);"
to allow these methods to be used in any perl code on the IC server?
