Worked a bit more on the Reefknot::Storage and Reefknot::Query modules. Not much though, as some of the modules I need to use are still horribly broken in CVS. The Reefknot team's talking about the need for a generic OO date/time module in Perl, separate from any iCal-friendly implementation we might build.
I'm starting to look for small Perl calendaring and date/time projects, asking their maintainers to come play with the Reefknot developers. I did a little of that. Also, I learned how to set up a list at perl.org.
Rich pointed out that there are many Perl modules that do date and time handling, but that there's no place for people who work on them to get together and talk about what's good, bad, and missing. So, I got the datetime@perl.org list set up.
