Inconsistent Code

Hi Again,

I cannot figure out why the date is only showing on the first (most recent) post in my “Latest Posts” list at the foot of the page:

https://www.rayah.org/rhemagarden/

Here’s the code

<div class="left">

		<h2>Latest Posts</h2>

		<ul class="block">

<?php
$myposts = get_posts('numberposts=5');

if ($myposts) :

	foreach ($myposts as $post) :

		setup_postdata($post);

		unset($categories);

		foreach (get_the_category() as $category)
			$categories[] = $category->cat_name;?>

<li><a href="<?php the_permalink();?>">
<span><?php the_title(); ?></span>
<em><?php the_date();?></em></a></li>
<?php endforeach;?>
<?php else : ?>
				<li>no entries</li>
<?php endif;?>
			</ul>

		</div>

Any help appreciated ??
Nicole
