I ran into this issue as I was implementing the conversion for bedework. 
The situation obviously arises during scheduling but might also arise 
with publishing a single instance.

I think the short answer is that the overrride must be a complete 
representation of the event/task as modified by the override. I did 
raise an issue with that. If the override has the start timezone 
modified then there's no way to determine the actual timezone of the 
master. In iCal the recurrence id has the timezone represented as the 
tzid parameter.

The suggestion made was to use a "recurrenceIdTimeZone" property to 
specify the timezone used for recurrence ids.
