Redeeming page field's preexisting value in saveReady hook

[hellomoto]

	function customPageSaver(HookEvent $hook) {
	 	$page = $hook->arguments(0);
	 	if ($page->template->name == 'event_instance' && $page->id !== 0) {
			$page->setOutputFormatting(false);
			$page->name = wire()->sanitizer->pageName(wireDate('Y-m-d', $page->date));

			if ($page->time_end < $page->time_start) {
				$hook->message('End AFTER starting.');
				$page->time_end = '';
			}
	 	}
	}
    $this->addHookAfter('Pages::saveReady(template=event_instance)', null, 'customPageSaver');

Can I set the $page->time_end to its previous value, rather than ''? I think I've done that before but forget how.

This old thread should get you started. However, I am not sure how you would be able to get the current value of the start time to compare against.
