Hi Robin, the function must return the string that you'd like to have  
inserted as the value in the column.  For example, to get the time,  
use something like (untested)

(defun my-org-column-cleaner (title value)
    (cond
      ((equal title "TIME")
       (if (and value (>= (length value) 20))
           (substring value 15 20)
          nil ; there was no value, or it was a short string
          ))
       (t nil)))
(setq org-columns-modify-value-for-display-function 'my-org-column- 
cleaner)
