Thanks!

I tried to paste your code into my .emacs and I received the following 
error when publishing :

"org-html--build-pre/postamble: Wrong number of arguments: (lambda nil 
(format "Last update : %s" (format-time-string "%d %b %Y"))), 1"

I don't know where is the problem. I tried then to do the same by 
modifying the variable "Org Export HTML Postamble Format". The default 
format is :

'(("en" "<p class=\"author\">Author: %a (%e)</p>\n<p 
class=\"date\">Date: %d</p>\n<p class=\"creator\">%c</p>\n<p 
class=\"xhtml-validation\">%v</p>"))

So I changed it to (with the idea to change the string format (%s) later 
if working) :

'(("en"<p class=\"date\">Last update: %s</p>"))

(which add to my .emacs :  '(org-html-postamble-format (quote (("en" "<p 
class=\"date\">Last update: %s</p>"))))

But it does not change at all the postamble ""Created: 2013-09-19 jeu. 
14:09"".

So I'm stuck!

According to `org-html-postamble' docstring, the function has to accept
one argument.

Again, according to `org-html-postamble' docstring, you need to set that
variable to t in order to use `org-html-postamble-format'. Then, by
looking at `org-html-postamble-format' docstring, you can see that only
%t, %a, %e, %d, %c, %v, %T and %C are allowed as format characters.

Whoops, that's what I get for posting untested code... As Nicholas
points out the function should take an argument, but in your simplest
case you can ignore it:

(defun my-org-html-postamble (plist)
  (format "Last update : %s" (format-time-string "%d %b %Y")))

Thanks.

I tried this new code (by pasting it into .emacs). But I have the 
default postamble in the result.

I tried then to achieve the same but by using org-customization which 
put into .emacs this :

'(org-html-postamble t)
'(org-html-postamble-format (quote (("en" "Last update : %d"))))

If it was working I would try to modify %d to have a %d %b %Y format. 
But  for now I have only "Last update : " without time...

I finally actually tried this myself... I'm guessing that your problems
are coming from pasting things without actually eval'ing them. I put
this in scratch:

(defun my-org-html-postamble (plist)
  (format "Last update : %s" (format-time-string "%d %b %Y")))
(setq org-html-postamble 'my-org-html-postamble)

And hit "C-x C-e" after both statements, and a test document exported
with the proper postamble:

<div id="postamble" class="status">
Last update : 21 Sep 2013
</div>

Can you make sure you've evaluated the forms?

I would have thought your org-customizations above would work, but
there are multiple ways to solve this problem, and perhaps you've got
competing solutions. Try reloading org, or worst case restarting emacs?

modify postamble in html export

[pw]

Hi,

I want to have a postamble in html with just the date (and without hours).

I already delete other informations in the postamble with these 
variables into my .emacs :
  '(org-export-author-info nil)
  '(org-export-creator-info nil)
  '(org-html-validation-link nil)

Now I have only the date left in the postamble but I want to change the 
format.

The default is : "Created: 2013-09-19 jeu. 14:09" and I want "Last 
update : 19 sept. 2013"

To do this I tried to set this variable :
  '(org-export-date-timestamp-format "%d %h %y")

But it is not working (and I have no idea how to put the "Last update :").

Could you indicate me how to achieve this. An issue is also I don't want 
to put this date format in all org-mode (I want to keep the default 
format for task and other stuff).

bye

You can override the whole thing by re-defining the `org-html-postable'
variable. Set it to a function which returns the string you want:

(defun my-org-html-postamble ()
  (format "Last update : %s" (format-time-string "%d %b %Y")))

(setq org-html-postamble 'my-org-html-postamble)

I didn't test that, but something like that ought to work.

HTH,
Eric
