One of my little open source projects is rem2ics, which converts the db from the remind calendaring app into RFC2445 iCalendar, which can be used by Mac iCal, Google Calendar, etc.

My app outputs DURATION attributes instead of DTEND attributes, because it maps better onto what remind hands it, and I didn't want to have to do the annoying calendar math.

As I say in my comment on that part:

 # It's convienient that RFC2445 defines DURATION, thus we
 # don't need to calculate DTEND, with awkward figuring out
 # crossing hours, days, months, year, etc.  Instead we
 # will let the iCalendar consuming application worry about it.
  

Well, according to the bug report I just got, it looks like both eGroupware and Sunbird get this wrong. Or maybe I get it wrong. I don't have time right now to look at it deeper, unless someone wants to spend a little money (that will change my priorites!)
