Adjust code to display excerpt and date/time

Hi

I was just wondering if someone could adjust this code to display an excerpt rather than the full content and to pull the date and time from a page.

I seem to be having trouble with it and any help would appreciated.

I got the code from here:
http://codex.wordpress.org/Function_Reference/get_pages#Displaying_Child_pages_of_the_current_page_in_post_format

<?php
    $mypages = get_pages('child_of='.$post->ID.'&sort_column=post_date&sort_order=desc');
    $count = 0;
    foreach($mypages as $page)
    {
        $content = $page->post_content;
        if(!$content)
            continue;
        if($count >= 2)
            break;
        $count++;
        $content = apply_filters('the_content', $content);
    ?>
        <h2><a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a></h2>
        <div class="entry"><?php echo $content ?></div>
    <?php
    }
?>

Regards
