To avoid this error, set the appointment option to Gregorian instead of Lunar. I ran into the same thing (although not with Eliot's .ics file). Outlook is unable to parse the VTIMEZONE object generated by iCal - despite the fact it conforms to 2445. What's alternately amusing and horrifying is the VTIMEZONE object's I've seen that Outlook can process are pretty goofy. For one thing the Outlook/Exchange-generated VTIMEZONE object uses a start date of Jan 1, 1601. This is hilarious. There are other problems with the iCalendar files generated by Microsoft, and with Outlook's attempts to read iCalendar files generated by means other than Outlook/Exchange. But this one is so wacky, I can't help but laugh - the help message quoted above is a close second. -- john noerenberg -- Statt des törichten Ignorabimus heiße im Gegenteil unsere Lösung: Wir müssen wissen, Wir werden wissen. -- David Hilbert, "Logic and the Understanding of Nature, Sep 1930 -- ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

Actually, the client I'm working on does do a pretty good job of laying out the events in IETF meetings. The reason for that is that I actually used the IETF meeting schedule as an example of a complex schedule that had to be displayed properly, and designed the system so that the IETF meetings look nice when displayed. The algorithm for doing that was of course designed to be generic enough to handle other complex schedules too. -- Cyrus Daboo ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

>Why would you want to have a calender without timezones??

Absolutely... Be that as it may, I was intrigued as to why Thunderbird did such a different job on the two files. A quick look at the code did not help. Anyway thanks for the effort.. very useful!

This may be because mine treats two sequential 1-hour meetings as a 2-hour meeting, and Eliot's treats them as 2 1-hour meetings. See l3vpn on Monday and mip6 on Tuesday evening. I originally wrote the agenda parser that's the basis of this .ics output when we switched to 1-hour meetings on Tuesdays because I could never tell whether a given meeting was one or 2 hours long. I have yet to find a client that has a good variable-length overlapping event rendering algorithm, especially with 8-9 events in the overlap. Apple's iCal usually does really well when there are 3 or 4. Bill ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

No responsibility if you miss your meetings. No promises to update it. But it works for me. Thanks for the file. Unfortunately it is not a valid iCalendar file as the VERSION property is missing. That property is required by the iCalendar specification (rfc2445 section 4.6). To fix this, just add the following line below the 'BEGIN:VCALENDAR' line: VERSION:2.0 In addition, each VEVENT component needs to have a UID property with a unique identifier in each one. Whilst the syntax of section 4.6.1 of rfc2446 implies that that parameter is optional, the description for the parameter itself (section 4.8.4.7) actually says it MUST be present. The Calisfy working group is attempting to fix ambiguities in the spec like that, amongst other things. I did 'fix' my version of the file with suitable changes and was able to import it correctly into my client. Also, I note there is a new updated agenda out that is different from the one you posted. BTW I think it might be worthwhile for the folks working on tools for IETF processes to look into having an automatic iCalendar generator for IETF agendas as a lot of people now have iCal capable clients that they could use to display the agendas.
