In Summary, I gather from Karen, the Drupal Calendar Moderator, there are two issues:

1. The .ICS headers are not correct and need (according to http://www.ietf.org/rfc/rfc2445.txt) :
'Content-Type: text/calendar; charset=utf-8';
'Content-Disposition: attachment; filename="calendar.ics"; ';

2. "DTSTART:20080229T141500Z" complies with the Ical spec but a "more common format is"
DTSTART;VALUE=DATE:20080229T141500Z
or
DTSTART;VALUE=DATE-TIME:20080229T141500Z
one issue is that ICAL is not conforming to the

Unfortunately, I do not have the programming skills to fix either.  Most people using ICAL with drupal will run into these problems when they upgrade to Calendar 2.0 or DateAPI 2.0, which fix the TimeZone issue and are currently release candidates.  1.9 / 2.0 are also not compatible with Google Calendars or other ICal services.

These do not seem to be listed as open issues for 1.9 or 2.0 when I click the issue list, but hope that we can still make the 2.0 final release.

I'm not a programmer and cannot do this myself, I'm volunteering to help a non-profit.  However, I can offer a $100 bounty if we can get this done for Civi2.0 and can offer any other assistance in testing or working it through with someone.

Quick report from battlefield: I managed to get Calendar running, mangled a bit with our iCal format and I think I managed to fix part of the issue. Need to leave the office in a couple of minutes, but will post more detailed update later today (evening in my timezone ;-) ).

Ok, it seems like I got it working with dev version of Calendar. Please take a look at drupal.demo.civicrm.org's feed and let me know if it works for you - you should be able to get it displayed properly in your install. If you want to update your install, wait for next beta or manually replace those two files with their current versions:
CRM/Utils/ICalendar.php
templates/CRM/Core/Calendar/ICal.tpl

The issue was solved by adding DATE-TIME attribute, as Karen suggested. It didn't become obvious to me at first place because of the testcase I chosen for my experiments. Looks like it triggered another bug with current (not dev) version of calendar and at some stage I got lost what's working and what's not. :-)  Anyways,  both versions should be working fine now.

There is still an issue with Google Calendar, which I'm going to investigate further.

Thx,

just saw an update from karen - interesting - she said the drupal Date module was the problem!  See: http://drupal.org/node/217898 . Wonder if there are 2 issues ?  I will try both the date patch and the civi patch and let you know.
