[TYPO3-calendar] Importing complexe events in Cal

[Kay Strobach]

Hello Mario,

i need to import a bunch of events regularly into cal (every 60 Minutes).

Example events (idx 2 and below often have two dates)
http://apps.drk-dresden.de/a+f+parse/

One solution would be to simply push the events into cal - but i'd like 
to use the API to be future proof ;)

What i found so far is the following:

  - cal has temporary events - very cool
  - tx_cal_event_service::createEvent($row, $isException)

But how do i add an additional date using the api to an event?
Is there any documentation about that stuff?

Regards
Kay
