[O] recurring floating appointments

[Carson Chittom]

I'm using the builtin org 7.8.11 in Emacs 24.  In an org file, I have
something like

* Recurring Events
#+CATEGORY: Meeting
** Monthly Third Thursday Meeting
   <%%(org-float t 4 3)>

This displays on my agenda fine.  However, that particular meeting
always happens at 10:00 AM, and I'd prefer to show it at that time in my
agenda, instead of an all-day event.  I looked through the documentation
for org-float (as well as diary-float in the Emacs manual), and I saw
nothing on assigning a time to a floating event.  I tried doing
something like

<%%(org-float t 4 3) 10:00-11:00>

but that didn't work.  Is assigning a time like this to an org-float
even possible?  Am I missing something?
