Ah. I see. I don't think there's any way make an item with a diary sexp
behave like a recurring timestamp. I think the best solution here would
be to create multiple items w/ todos, as Stephan suggested in his post.

I imagine one way to do this would be to create two items with repeating
timestamps:

--8<---------------cut here---------------start------------->8---
* TODO 10:00am Class
  SCHEDULED: <2009-11-09 Mon +1w>
* TODO 10:00am Class
  SCHEDULED: <2009-11-11 Wed +1w>
--8<---------------cut here---------------end--------------->8---

I'm sorry to say that I'm not sure where it's documented. But org-mode
does scan the headline for time of day information.

Best,
