Put the following in your .emacs:

(setq dired-mode-hook 'dired-mode-hook)

(defun dired-mode-hook ()
  "Define dired extensions"
  (setq case-fold-search t)		; Why is this not done?
  (define-key dired-mode-map "t" 'dired-sort-by-time)
  (setq dired-mode-hook nil))

(defun dired-sort-by-time (arg)			; t
  "Reread directory and sort by time. Reverse sort with prefix."
  (interactive "P")
  (let ((dired-listing-switches
	 (concat dired-listing-switches "t" (and arg "r"))))
    (revert-buffer)))
