title: UIDatePicker vs. UIApplicationSignificantTimeChangeNotification
body: <p>I'm handling <strong>UIApplicationSignificantTimeChangeNotification</strong> in my app and all the other screens in the app are gracefully refreshed when midnight comes. The one I have trouble with is with <strong>UIDatePicker</strong>. <strong>UIPickerView</strong> has <strong>refreshAllComponents</strong> method which I use in another screen to make an update on midnight change. I would like to have the same for <strong>UIDatePicker</strong>, but unfortunately I couldn't find a way to refresh it, and <em>Today</em> remains <em>Today</em>, although it is already <em>Yesterday</em>. Any way out?</p>
