[Orgmode] Timeline view > Headers not time-sorted

[Francesco Pizzolante]

Hi,

I'm using org-mode version 6.25a and I'm getting the following
problem: in the timeline view of a single Org file, headers are
not time-sorted.

Here's an Org file example:

--8<---------------cut here---------------start------------->8---
* P1
  :LOGBOOK:
  CLOCK: [2009-04-30 Thu. 13:00]--[2009-04-30 Thu. 15:00] =>  2:00
  :END:

* P2
  :LOGBOOK:
  CLOCK: [2009-04-30 Thu. 10:00]--[2009-04-30 Thu. 12:00] =>  2:00
  :END:
--8<---------------cut here---------------end--------------->8---

With the previous Org file, I end up with the following timeline
view (C-c a L):

--8<---------------cut here---------------start------------->8---
-------------------------------------------------------------------------------
Thursday   30 April 2009
  Clocked:   (2:00) P1
  Clocked:   (2:00) P2
--8<---------------cut here---------------end--------------->8---

I would expect to see P2 before P1 in the timeline.

Could you tell me what I'm doing wrong?

Thanks a lot,
Francesco
