No, it's not, and is ignored by Kronolith. Since attributes with this  
prefix are usually per-calendar properties from Google, my best bet  
is, that this the calendar's default timezone. It might indicate which  
timezone the user wants to use. But since we don't have per-calendar  
timezones, just per-user and per-event timezones, there isn't anything  
we could do with this information. Let alone that it isn't any standard.

It already uses the (server's) default timezone.
