The exchange rates are not actually the reason for the slow start-up
(the exchanged rates are looked up lazily). Tackling the slow start-up
time is planned for the next version of Units, but at the moment I
still don't have enough time (I may find some in a month or so).

As for date calculations, currently Units only has a notion of
duration, and it seems only up to days. The current version doesn't
define interaction with actual dates, like adding a month to a today's
date and such. You might want to look at Active Support for the
moment.
