Want to Show Post Dates on Page that Shows One Category

Sorry about the long title. I’ll explain.

I have a client that wants a page to show posts from a certain category on a page other than index.php. I have set it up with a page template (named “blog”) to pull posts listed as a certain category. Here’s the code –

<?php query_posts('cat=20&showposts=5'); ?>
<?php while (have_posts()) : the_post(); ?>
<?php endwhile; ?>

The problem here is that I get a page with posts but they don’t show the date. I’m guessing that I’m going to need to have

<?php the_date(); ?>

somewhere in there I just don’t know where. Does anybody have any ideas? Thanks in advance.
