How to show sticky posts first?

[jasmines]

I want to extract posts from my network, ordering them by date but I want sticky posts to be shown first. I'm trying this:

$args = array(
        'post_type' => 'post',
        'post_status' => 'publish',
      'network' => true,
        'orderby' => 'date',
        'order' => 'DESC',
        'post__in' => get_option( 'sticky_posts' ),
        'ignore_sticky_posts' => false
    );

No luck...
