I created a new post type named “Video”.

When I create post for the post type, posts is ordered by title ASC.

Is it possible to order posts by date DESC please ?

register_post_type('Videos', array(
    'labels' => array(
        'name' => _x('Videos', 'post type general name'),
        'singular_name' => _x('Video', 'post type singular name'),
        'add_new' => _x('Ajouter', 'Video'),
        'add_new_item' => __('Ajouter une video'),
        'edit_item' => __('Éditer une video'),
        'new_item' => __('Nouvelle video'),
        'view_item' => __('Voir le lien de la video'),
        //'search_items' => __(' Video'),
        'menu_name' => 'Video'
    ),
    'public' => true,
    'show_ui' => true,
    'capability_type' => 'post',
    'hierarchical' => true,
    'rewrite' => array('slug' => 'video'),
    'query_var' => true,
    'supports' => array(
        'title',
        'editor' => false,
        'excerpt' => false,
        'trackbacks' => false,
        'custom-fields',
        'comments' => false,
        'revisions' => false,
        'thumbnail' => false,
        'author' => false,
        'page-attributes' => false,
    ),
    'taxonomies' => array('post_tag')
   )
 );
