Hi,

This patch implements warn time for org appt. It only works on emacs bzr
(the variable appt-warning-time-regexp appears in it). You need to add
the warntime in the text of the entry, like so :

* doctor warntime 10
  <2012-02-19 10:00>

or 

* doctor warntime 10 <2012-02-19 10:00>

The patch is not fit to be included in org. I am submitting it in case
it interests others to have the functionality.
