Order of posts query not working

I’m trying to get all posts in a certain category and display the titles in a certain order.

Everything works but the ‘orderby’ bit. No matter what values I put there, nothing changes.

Here’s my code. Help appreciated

<?php global $post;
$args = array( 'posts_per_page' => 1000, 'category' => 3, 'orderby' => 'date', 'order' => 'asc' );
$myposts = get_posts( $args );
foreach( $myposts as $post ):?>
<div class="obitsidebaritem">
<?php setup_postdata($post); ?>
<a>">
<?php echo get_the_post_thumbnail($post->ID, 'thumbnail');?>
<p><?php the_title();?></p></a>
</div>
<?php endforeach; ?>
