Hi Pat,
The minute hand on your clock has prbably slipped on its collet. The only real repair is to remove the hand reposition it on the collet and re-rivet it.

When the clock strikes move the minute hand to the correct position hr or half hour stop the clock wait while the time catches up, and then restart the clock it will work correctly.
