[Orgmode] clocksum bug in agenda-view with log-mode on

[iemacs]

I'm using 6.05 currently.

I've found a problem with the clocksum function in agenda-view with
log-mode.  The following org file has two tasks with clock-time events:

#+COLUMNS: %25ITEM(Task) %CLOCKSUM
* TODO task1
  :CLOCK:
  CLOCK: [2008-06-21 Sat 15:37]--[2008-06-21 Sat 16:37] =>  1:00
  CLOCK: [2008-06-22 Sun 19:37]--[2008-06-22 Sun 20:37] =>  1:00
  :END:
* TODO task2
  :CLOCK:
  CLOCK: [2008-06-22 Sun 18:00]--[2008-06-22 Sun 19:00] =>  1:00
  CLOCK: [2008-06-22 Sun 21:00]--[2008-06-22 Sun 22:00] =>  1:00
  :END:

In the Agenda-View, the clocksum include more clock-time event for
calculation, and it doesn't limit the calculation to the specific day in
agenda-view.  It shows like this:

Task                    | CLOC |
Day-agenda (W25):
Sunday     22 June 2008 | 6:00 |
TODO task2              | 2:00 |
TODO task1              | 2:00 |
TODO task2              | 2:00 |
