[kronolith] CALDAV without a DTSTART

[Paul Ronald]

I have a problem syncing my calendars using  CALDAV.
My problem is caused by an invalid timezone definition in the response ics:

BEGIN:DAYLIGHT
TZOFFSETFROM:+0100
TZOFFSETTO:+0200
TZNAME:CEST
END:DAYLIGHT

I have read this RFC rfc5545 says "

      The "VTIMEZONE" calendar component MUST include the "TZID"
      property and at least one definition of a "STANDARD" or "DAYLIGHT"
      sub-component.  The "STANDARD" or "DAYLIGHT" sub-component MUST
      include the "DTSTART", "TZOFFSETFROM", and "TZOFFSETTO"
      properties."


Best regards
