Right - I just did a test and indeed if you create a new calendar and add a 
single event with a timezone, it does not include the VTIMEZONE in the ics 
file it creates in its own calendar store. However, if you 'Export' the 
calendar from the iCal.app, then it does include a VTIMEZONE. The VTIMEZONE 
appears to be correct, but contains only the minimum amount of information 
to cover the time for the event. Arguably this is not a bug as it is free 
to do whatever it wants in its own calendar store.

WRT naming of timezones on different OS's - hopefully with a standardised 
timezone registry we can solve that issue and also remove the need to 
always send the VTIMEZONE data by value (as opposed to by reference to the 
registry entry).
