Thats a shame on facebooks part. In my case probably all events will  
originate from the same timezone. I am guessing that for most users  
this scenario is the most likely (or not?!). Would it be possible and  
usefull to introduce a user definable "standart correction factor"  
with wich Facebook events are corrected so that the calendar works at  
least for event  creators in one timezone as a workaround?
