    datetime: Fix warning running callback before objects are created
    
    The following warning occurs when the datetime panel is created:
    (gnome-control-center:3173): GLib-GIO-CRITICAL **: 09:18:38.531: g_settings_get_value: assertion 
'G_IS_SETTINGS (settings)' failed
    
    This is due to the callback being called before the settings object is created
