iCal won't accept my ics file

Question

My web app generates ics files. These can be read successfully by Google Calender, but not iCal, which shows the error "iCal can’t read this calendar file. No events have been added to your iCal calendar.".

Why doesn't my ics file load in iCal?

Here is the file contents:

BEGIN:VCALENDAR
VERSION:1.0
PRODID:-//Third Workplace//EN
BEGIN:VEVENT
SUMMARY:Meeting at Third Workplace in Office #4
DTSTART;TZID=UTC;VALUE=DATE-TIME:20120820T160000Z

UID:[email protected]
LOCATION:Office #4 at Third Workplace Contra Costa Centre

Here is the original, binary version.

Answer 1

Change that version to 2.0, and watch the magic happen :-)
