When I tried to import my Evolution calendar.ics file, it failed to upload with
the error: Error parsing iCalendar data: Event start time should precede end time.

I traced the cause back to a number of events in my file that have no time
associated with them (Like holidays etc).

A failing event looks like this:
BEGIN:VEVENT
UID:20041115T212328Z-27508-1002-25892-6@cronos
DTSTAMP:20041115T212303Z
LAST-MODIFIED:20050727T125728
SUMMARY:Moederdag
DTSTART;VALUE=DATE:20030815
DTEND;VALUE=DATE:20030815
RRULE:FREQ=YEARLY;INTERVAL=1;WKST=SU
CLASS:PUBLIC
SEQUENCE:1
CREATED:20050727T125728
END:VEVENT

I have this event in attached ICS file
