Add to previous posts under post

Try to add date_query to the $qry in the solution mentioned here.

$qry = new WP_Query(
       array(
            'cat'            => $current_post_categories[0],
            'posts_per_page' => 2,
            'post__not_in'   => array( $current_post_id ),

            'date_query' => array(
                                 array(
                                     'before'     => $post->post_date,
                                 ),
                            ),

              ));
