There was a bug in the Horde_Timezone package that prevented the  
file:/// urls from being loaded correctly. This has been fixed in Git.

No. This extension provides the updated timezonedb that is used by php  
internally. It is binary data that cannot be parsed into the format  
that is needed to create the RRULEs for the vTIMEZONE structure - is  
is one of the reasons that Horde_Timezone was developed in the first  
place.
