Sunbird embeds the definition of the timezone it uses in the posted  
iCalendar file (like most clients). The name it uses is completely  
arbitary from a specification point of view, its just a reference to  
the contained definition.
However, most clients use a non-arbitary name but something sane  
containing the real timezone (eg America/New_York).

Now the proper thing would be to parse and use the embedded timezone  
definition (convert it into an NSTimeZone object). But this isn't  
exactly trivial (well, maybe it isn't too hard).
So ZideStore is lazy and just tries to lookup the timezone by name ...

I think what would be useful is maintaining an alias map in a default  
(mapping external iCal IDs to existing NSTimeZones).

Greets,

PS: in GroupDAV we require that events are transmitted in UTC, except  
for recurrences which require a timezone.
