the_date and the_title returning empty strings

Hi,

I am trying to display the latest posts of my WordPress blog on an external page. I got the code below from:
http://codex.wordpress.org/Integrating_Wordpress_with_Your_Website

<?php $posts = get_posts('numberposts=10&order=ASC&orderby=post_title'); ?>
<?php
	foreach ($posts as $post) : setup_postdata( $post );
?>
date: <?php the_date(); ?>
title: <?php the_title(); ?>
excerpt: <?php the_excerpt(); ?>
<?php
	endforeach;
?>

Only the excerpt is show, the title of the post “Hello world!” and the date “January 17, 2014” is not shown.

Can anyone help?
Thank you
