[Orgmode] possible bug of display time-range appt in agenda

[Levin]

Put something in the org buffer:
** Do something <2007-10-01 11:30-12:20>

then in the agenda, only "Do something" is displayed, without showing the appt 
time.

I trace the code and find out that: 
 (org-get-time-of-day "<2007-10-01 11:30-12:20>")
which return nil cause this probem.

I do not know if this bug has been mentioned or resolved. I'm posting here in 
case that it is not :)

PS. I did a patch, which solves the problem. Yet it is a bit ugly :)

(It is the diff of org-get-time-of-day function. line number may be wrong.)
