Show date for articles not for pages

Hi

I know there are some threads about this, but I haven’t managed to figure it out yet.

I have my template which is only one all-mighty index.php with its associated style sheet.

My articles show the date and author which is all fine, but the pages does too. I don’t want them to show nothing else that the page name and their content.

My list page code looks like this:

<?php wp_list_pages('exclude=10'); ?>

I don’t tell it to show the date but because I tell the articles to have the date and author shown like this, the pages also do it:

<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); ?><h1><?php the_title(); ?></h1>

<?php the_time(‘F jS, Y’) ?> by Johan Niemi`

Is there a simple solution?
