[Orgmode] setting time for agenda items

[bastre]

org-mode users:

I have recently started using org-mode instead of MS Outlook.  I like what I 
see.  I have a question that I cannot seem to find the answer to: For scheduled 
events (org-schedule function), how do I set the appointment time?  For 
example, I have a doctors appointment on 02/23/2007 at 2:15pm. How do I include 
the 2:15pm on the calendar- not just the date?  I verified the 
org-agenda-include-diary is set to "t".

Thanks so much in advance!
