Query Posts in Category minus Current Year

I'm trying to show all posts in a category except the posts from the current year...
This isn't working...


$current_year = date('Y');
$my_query = new WP_Query( "cat=3&exclude=$current_year&order=DSC" );
while ($my_query->have_posts()) : $my_query->the_post(); ?> 

<div <?php post_class() ?> id="post-<?php the_ID(); ?>">
<small><?php the_time('F jS, Y') ?></small>
<h3><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a></h3>
<div class="entry">
<?php the_content(''); ?>
</div><!-- end entry -->
<?php edit_post_link('Edit this entry.', '<small>', '</small>'); ?>
</div><!-- end post -->
<?php endwhile; ?>
