Maybe this will help:

;; ---------------------------------------------------------------------------- 
DISPLAY-TIME
(display-time)
(defun esf/org-clocking-info-to-file ()
  (with-temp-file "~/tmp/clocking"
    ;; (message (org-clock-get-clock-string))
    (if (org-clock-is-active)
        (insert (format "org: %d/%d min" 
                        (- (org-clock-get-clocked-time) org-clock-total-time)
                        (org-clock-get-clocked-time))
                )
      ) ;;(org-clock-get-clock-string)
    )
  )
(add-hook 'display-time-hook 'esf/org-clocking-info-to-file)
--8<---------------cut here---------------end--------------->8---

I use this to place information on clocking at the top of my display
(using dzen2 with ratpoison).  I have minimal space so only include
the time information, not the full information which typically
includes the org-heading being clocked.

This doesn't work properly if you have two emacs instances but I can't
be bothered to improve it as I *never* have two or more emacs
running...  that's what emacsclient is for, after all... ;-)

HTH,
