Any TZID is valid, because it's just a label.

We do support the Olson timezone names (see IANA) and the Windows and  
Lotus aliases, see Horde/Date.php.

No.

Yes. This may happen if we come across an exception of a recurring  
event, and can find the base event, but that base event no longer is a  
recurring event. Please file a ticket.
