Subject: [PATCH]add a custom function to get date string in agenda
Date: Wed, 12 Sep 2007 11:08:07 +0800	[thread overview]
Message-ID: <200709121108.08018.zslevin@gmail.com> (raw)

I have a special need of customizing date string in agenda (the date format 
string is even not enough because I'd like other date format than Gregorian). 
So I add a custom variable org-agenda-date-string-function,
bind it to org-agenda-date-string to preserve current org behaviour.

Then in my org conf file, I add:
(defun my-org-agenda-date-string (date)

(setq org-agenda-date-string-function 'my-org-agenda-date-string)

Hope it helps.
