I whipped something up that should work for you.

You need to evaluate the code below and then the below table will work
for you.

(defun ba/org-timerange (s &optional in-min)
  (let* ((re "^\\(.*?\\)--\\(.*?\\)$")
         (start (replace-regexp-in-string re "\\1" s))
         (end (replace-regexp-in-string re "\\2" s))
         (start-in-min (org-hh:mm-string-to-minutes start))
         (end-in-min (org-hh:mm-string-to-minutes end))
         (diff-in-min (- end-in-min start-in-min)))
    (if in-min
        diff-in-min
        (format "%.2f" (/ diff-in-min (float 60))))))

| date             | client | desc  | timerange                                 
     |  H:M | in dec |
|------------------+--------+-------+------------------------------------------------+------+--------|
| <2009-08-26 Wed> | benny  | foo'd | <2009-08-26 Wed 21:55>--<2009-08-26 Wed 
21:58> | 0:03 |   0.05 |
#+TBLFM: $5='(org-minutes-to-hh:mm-string (ba/org-timerange $4 
t))::$6='(ba/org-timerange $4)

If you're on the table and you press C-u C-c C-c and it should put the
correct info at the respective places.

Now what I recommend is using autocalc instead so you don't have to
worry about doing this. This would require you to change your table to
the following format:

|   | date             | client | desc   | timerange                            
          |  H:M | in dec |
|---+------------------+--------+--------+------------------------------------------------+------+--------|
| # | <2009-08-25 Tue> | benny  | foo'd  | <2009-08-25 Tue 20:55>--<2009-08-25 
Tue 23:58> | 3:03 |   3.05 |
| # | <2009-08-26 Wed> | bar    | quux'd | <2009-08-26 Wed 22:10>--<2009-08-26 
Wed 22:14> | 0:04 |   0.07 |
#+TBLFM: $6='(org-minutes-to-hh:mm-string (ba/org-timerange $5 
t))::$7='(ba/org-timerange $5)

The "#" in the first column achieves this. See (info "(org)Advanced features")
for more information.
