You don't need to do that - you can do it all in IB.

Drag the default date formatter and drop it on the column, which will
format the column with the undesired long format.

Switch your nib window to the outline view, and tunnel through the
outline until you find your scroll view > table view > table column,
which should have an NSDateFormatter inside it.  Select that item, go
to the Custom Subclass panel, select your new subclass.  Done.

(This trick works in other places that have formatters as well, besides
table columns)
