Apart from what Pascal suggested, you could try these:

(defun insert-current-time ()
  (interactive)
  (destructuring-bind
        (sec min hour day month year dow dst zone)
      (decode-time)
      (insert (format "%02d:%02d:%02d" hour min sec))))

(defun insert-current-date ()
  (interactive)
  (let ((days '((0 . Sunday)
                (1 . Monday)
                (2 . Tuesday)
                (3 . Wednesday)
                (4 . Thursday)
                (5 . Friday)
                (6 . Saturday)))
        (months '((1 . Jan)
                  (2 . Feb)
                  (3 . Mar)
                  (4 . Apr)
                  (5 . May)
                  (6 . Jun)
                  (7 . Jul)
                  (8 . Aug)
                  (9 . Sep)
                  (10 . Oct)
                  (11 . Nov)
                  (12 . Dec))))
    (destructuring-bind
          (sec min hour day month year dow dst zone)
        (decode-time)
      (insert (format "%s, %d %s %d"
                      (rest (assoc dow days))
                      day
                      (rest (assoc month months))
                      year)))))

You could, of course, combine these as:

(defun insert-current-time-date ()
  (interactive)
  (insert-current-time)
  (insert (format "  "))
  (insert-current-date))

Or whichever way you want them.

P.S. Suggested improvements gladly accepted.
