Importing Icalendar events

I'm attending the Educause 2003 annual conference in Anaheim in November. This is a huge conference, with lots of interesting sessions over most of a week. Educause has provided a nice itinerary-builder on the Web for the conference, that allows you to browse the program and select the items you want to attend. You can then view your itinerary, or you can export your itinerary as an Icalendar format file.

Icalendar is the Internet Calendaring and Scheduling Core Object Specification (RFC 2445), which is supposed to provide an interoperable format for calendar events (note that this is only one of a whole bunch of Internet specifications for calendaring).

So after building my itinerary for the conference, I thought I'd import it into my calendaring system. Here at UW Computing & Communications we use the product formerly known as Corporate Time, now known as Oracle Calendar. This product says it knows how to import Icalendar format files, so I saved the .ICS file to my desktop and told Oracle Cal to import all events in the file, and I get "No valid entries to import."

OK, I think to myself, maybe this is a peculiarity of the OS X version of the product, so I go off and try the same thing on the Windows version, with the exact same result (nice to know they're at least consistent!).

I then try importing the same file into Apple's iCal calendar - boom, zap, pow, it goes in no problem and lists all of the events.

Hmmm...has anybody out there actually succeeded in importing Icalendar files into Oracle Calendar?
