You are missing the call to timer-set-time, I think.

Thanks... I see, it seems like every time that the display-timer runs it updates its interval. That doesn't seem very efficient, but there could be a good reason why they did it that way.

For the time in the minibuffer, this seems to work:

#+BEGIN_SRC emacs-lisp
(with-current-buffer " *Minibuf-0*" (insert (format-time-string "%H:%M")))

(run-at-time (timer-next-integral-multiple-of-time (current-time) 60)
              60
              (lambda ()
                (with-current-buffer " *Minibuf-0*"
                  (erase-buffer)
                  (insert (format-time-string "%H:%M")))))
#+END_SRC
Best,
