so picky ;) Maybe something like this will put that stamp in a comment
that won't export.

#+BEGIN_SRC emacs-lisp
(defun j-add-ts ()
  (save-excursion
    (re-search-forward "#\\+END_SRC")
    (forward-line)
    (beginning-of-line)
    (when (looking-at "# Last run:")
      (kill-line))
    (insert (concat
             "# Last run: "
             (format-time-string "[%Y-%m-%d %a %H:%M:%S]" (current-time))))))


(add-hook 'org-babel-after-execute-hook
          'j-add-ts)

;(remove-hook 'org-babel-after-execute-hook
;         'j-add-ts)
#+END_SRC
