Well, I use the following, which can be placed in your ".emacs" file.
It's sort of a hack, but it works.  

The "s" key in the dired keymap is defined to call "dired-sort", which
toggles the arguments to ls(1) between their normal dired value and a
set which sorts by date.  Each time you press the "s" key the
arguments are toggled, ls(1) is called, and the results displayed.
The ls(1) arguments are local to each dired buffer.  Enjoy!

-------------------- Cut Here --------------------

(load "dired")
(make-variable-buffer-local 'dired-listing-switches)
(setq-default dired-listing-switches "-als")
(define-key dired-mode-map "s" 'dired-sort)

(defun dired-sort ()
  "Alternates dired listing order between sorted-by-name
and sorted-by-date."
  (interactive)
  (setq dired-listing-switches
	(if (string-equal dired-listing-switches "-als")
	    "-alts"
	  "-als"))
  (revert-buffer))
--
