Then you have a big problem, very big. No user should ever EVER have administrator power. An administrator user can revert any change you make in Local Security Policy and regain the ability to change the time.
You already lost your ability to control these computers. Either take away administrator power and find a way to make your old broken POS applications work, or give up now.
