How to change standard date

How to change standard date

[Cecil Westerhof]

I would like to display the standard displayed date to local date, but I
can not get it to work.

I tried:
  (setq gnus-treat-date-local head)
But this gives:
    gnus-treat-predicate: "head" is not a valid value

I tried:
  (setq gnus-treat-date-local "head")
But then all headers are displayed, instead of only the default ones.

I tried:
  (setq gnus-treat-date-local t)
This looks the best, but there is an hour difference with 'W T l'.

So what is the correct way to get default the local date displayed?

Properly this is the correct way. I tried that with messages I already
read. When using it with unread messages it seems to work.

What puzzles me is why the documentation
(http://www.gnu.org/software/emacs/manual/html_node/gnus/Customizing-Articles.html)
says:
     gnus-treat-date-local (head)

 (setq gnus-treat-date-local 'head)

I'd guess.

That works. But the documentation is not very clear then. Because for
nil I do not put a '. So instead of talking about head, it should be
about 'head.

You could though.
nil is a variable that just evaluates to the symbol 'nil (eq 'nil nil)

the same goes for t.

I personally don't feel confused by a symbol, a string and a variable,
but because someone is going to say it, I'll do it:

Make a suggestion on how to improve the documentation. But beware: The
completely documentation uses the `foo' syntax for functions and
symbols.

One needs to be a little bit familiar with Elisp:

"   In Emacs Lisp, `nil' and `t' are special symbols that always
 evaluate to themselves.  This is so that you do not need to quote them
 to use them as constants in a program."

Use customize (`M-x customize-variable RET gnus-treat-date-local RET',
you can simply click on this in Gnus) or read (info "(gnus)Emacs for
Heathens"), especially...
