Horde_Alarm has been added with Horde 3.2. But we maintain backward  
compatibility in all H3 applications with any Horde 3.x version, i.e.  
also with Horde versions before 3.2. Thus you can't simply assume that  
Horde_Alarm exists in Kronolith code.
Beside that, since I implemented the iCalendar patch differently, the  
Kronolith patch has to be updated to reflect that.

Exactly, and this already happens, e.g. in  
Kronolith_Driver_sql::deleteEvent(). You can use the Horde_Alarm  
handling there as a blueprint for your own changes in the snoozing code.

Yes, but that has nothing to do with this request anyway.
