I've written a couple of Perl modules that do low-level date stuff, way below the high-level DateTime concept. I'd appreciate a review of my modules by the date experts on this list. The modules are Date::JD, which does conversions between several flavours of Julian Date, and Date::ISO8601, which implements the ISO 8601 calendrs in terms of Chronological Julian Day Numbers. They can be found at <http://search.cpan.org/~zefram/>. Thanks.
