Hi,

I'm experimenting with column view of a daily agenda and effort 
estimates.  I'm using this in my .emacs:

;; Effort Estimates
(setq org-global-properties
               '(("Effort_ALL". "0 0:15 0:30 0:45 1:00 2:00 3:00 4:00 
6:00 8:00")))

;; Column view for effort estimates
(setq org-columns-default-format "%80ITEM(Task) %2PRIORITY %TAGS 
%10Effort(Effort){:} %10CLOCKSUM")

I'd like to replace CLOCKSUM with a column that shows me just the time 
spent on the task *today* (not all the time ever spent on the task). 
I've read about CLOCK_MODELINE_TOTAL: today, but I'm not sure how to 
apply that.

Screen shot of what I've got now:



Thanks for any pointers!
