I've got a public ical at: http://m.fwckungfu.com/calendar.ics
This works in Google Calendar and in the iCalendar Validator but when I try to import this as a file in Apple iCal I get this message:
"Error subscribing to the calendar
Data downloaded from http://m.fwckungfu.com/calendar is not valid."
WTF? Who's ass have I not kissed to get this working in Apple iCal? Does anybody know any reason why Apple iCal is being so trixy?
Actually, the feed currently does not validate: it specifies a TZID for an UTC time, which is forbidden as per section 3.2.19 of RFC5545. Both the validator you link to and my more restrictive one at http://arnout.engelen.eu/icalendar-validator point that out.
Great! Thanks. I must have been sleepy when I last looked into it.
