Connecting jquery wordpress regularly?

Question

JavaScript

Why does jQuery not work with this option?

add_action( 'wp_enqueue_scripts', 'dipped_enqueue_styles' );
function dipped_enqueue_styles() {
    wp_enqueue_script( 'jquery' );
    wp_enqueue_script( 'my_js', get_stylesheet_directory_uri() . '/script.js', array( 'jquery' ), time(), null, true, );
}

when I connect jquery I copy it to / script.js everything works,

what am I doing wrong?
