Add date and time to post-title on non-static front page (twenty twelve)

How can I add the date and time of the post to the post title of the posts on the front page (non-static) of twenty twelve?

I have successfully added it to the single post page by adding a php call to the content.php file’s entry-header div like so:

<?php the_post_thumbnail(); ?>
			<?php if ( is_single() ) : ?>
			<h1 class="entry-title"><?php the_time('F j, Y'); ?><br />
			<?php the_title(); ?></h1>
			<?php else : ?>

Once again, this changes the single post page but not the appearance of post-titles on the front-page.

Thanks!
