That could simply be done using `message'.  One should take care of not
cluttering *Messages* and avoid erasing other messages.

I would try starting like this:

--8<---------------cut here---------------start------------->8---
(progn
  (defvar current-time-string "")
  (run-with-timer
   1 1
   (lambda ()
     (let ((message-log-max nil))
       (unless (minibuffer-window-active-p (minibuffer-window))
         (when (member (current-message)
                       (list current-time-string nil))
           (message "%s" (setq current-time-string
                               (current-time-string)))))))))
--8<---------------cut here---------------end--------------->8---

Alignment and combining with other messages could be done too.

Just an idea, admittedly this code is not super elegant.


Michael.
