and each offer some simple ways to hack the elisp variable
"dired-listing-switches" but I like mine better because it
makes no permanent changes to that variable.  (Small, too!)

Here it is:

; Make the "t" key sort the current dired listing by date.
; It takes effect just this once, so "g" will be unchanged.
(defun dired-sort-by-time ()
  "Redisplays a dired listing sorted by time."
  (interactive)
  (let ((dired-listing-switches
	(concat dired-listing-switches "t")))
    (revert-buffer t t)))
(setq dired-mode-hook '(lambda()
  (define-key dired-mode-map "t" 'dired-sort-by-time)
  ; Add other dired-mode-map customizations here...
))
