In xCal (and therefore Kolab Format), the timezone is a per-date setting. (So 
it has to be specified for each date, and there is no such thing as an events 
global timezone setting). I suggest to just take the dtStart timezone, because 
dtEnd MUST be of the same timezone as dtStart, which basically results in 
dtStart containing the events global timezone. Note that created and dtstamp 
MUST be UTC and exdate MAY be of another timezone.
