GeneralizedTime can be pretty inconvenient when all you want to store is a 
date (for a birthday, etc.) or only a time. There doesn't appear to be any 
standardized syntax just for these purposes. I recall lots of discussion of 
this topic on the LDAP lists and also the Mozilla Calendar discussion lists a 
long time ago. The problem being that GeneralizedTime requires both the date 
and time to be specified, and in a calendar application it's not clear that 
you actually want the time.

E.g., if all you want is for your calendar to remind you of someone's 
birthday, you just need it to tell you on that given day. Your calendar 
program might put up an alert at 00:01 local time on that date. But "00:01 
local time" is a floating time, while GeneralizedTime requires a specific time 
zone...
