The best way is to make new class based on timer. Than add it in run-time to any object that is global and exists all the time application runs. In your case this may be main top-level form. If modal form opened - this is not a problem, timer event will fire anyway.

Than, in your class in timer event check datetime() and shutdown application. Be sure no errors during forcing of form close, and no 'table open' dialog boxes appear because thay will prevent automatic shutdown requiring user interaction. When some form have data unsaved, that form should not show dialog boxes, so you will need a way to indicate that you're in shutdown mode. I usually use global logical variable flag for that. When it is .T., I avoid any dialog boxes and revert any changes in tables.

Only cases when timer event will not fire - Windows Open dialog boxes (like file selection by GetFile(), color selection by GetColor, diirecory selection by GetDir() etc.) It aso will not work whan application hangs up.

As you see, this task is not so easy. In one of my applications I made 'companion' Windows application, that tries to shutdown any VFP applications on computer at special time. When some application failed to shutdown because dialog boxes, that application will be killed as Windows process to free resources anyway.
