AFAIK what was implemented so far is a way to display the clocking time
against the effort estimate.

If you have an effort estimate, this is what it does in the modeline:
it tells you that your running clock is 9 minute and that the effort is
one hour.

With an effort estimate already in place, this is what it does.  And
when you reach the amount of estimated effort, you get a warning.

The steps are these:

- create a task
- add an effort estimate
- clock in

Let me know if this needs to be refined.

What I find not practical in the current set up is that you have to set
an effort estimate *manually* in order to get something like tea-time
provides.  I added a new hook on the repo: org-clock-in-prepare-hook
which makes it easy to modify the task effort property.  

Examples:

--8<---------------cut here---------------start------------->8---
;; Using this hook will set a default effort estimate of 1:00 
;; to each task you clock in and has no effort property.
(add-hook 'org-clock-in-prepare-hook 
          'my-org-mode-add-default-effort)

(defvar org-clock-default-effort "1:00")

(defun my-org-mode-add-default-effort ()
  "Add a default effort estimation."
  (unless (org-entry-get (point) "Effort")
    (org-set-property "Effort" org-clock-default-effort)))
--8<---------------cut here---------------end--------------->8---

--8<---------------cut here---------------start------------->8---
;;; Using this hook will let the user 
(add-hook 'org-clock-in-prepare-hook 
          'my-org-mode-ask-effort)

(defun my-org-mode-ask-effort ()
  "Ask for an effort estimate when clocking in."
  (unless (org-entry-get (point) "Effort")
    (let ((effort 
           (completing-read 
            "Effort: "
            (org-entry-get-multivalued-property (point) "Effort"))))
      (unless (equal effort "")
        (org-set-property "Effort" effort)))))
--8<---------------cut here---------------end--------------->8---

I have pushed this example to org-hacks.org on Worg.

HTH,
