Help with date coding and styling

Hello,

I’m trying to figure out how to get the date to show up to the left of the post title, styled a certain way. I got this to work on a genesis theme, but I’m new to twentytwelve and can’t quite seem to sort it out.

Here’s the code in a genesis (prose) theme that worked nicely before:

add_action( 'genesis_before_post_title', 'child_before_post_title' );
function child_before_post_title() {
   if ( ! is_page() ) { ?>

   <div class="entry-meta">
        <span class='day'><?php the_time('j');?></span>
         <span class='month'><br/><?php the_time('M'); ?></span>
     </div>

   <?php }
}

That, with some CSS of course, resulted in this: https://elevensixty.com/date-comment.png (minus the comment stuff which I did elsewhere). The code also made sure the date only showed on post pages, not static pages where it wasn’t needed.

In twentytwelve, I am trying to accomplish something similar. Here is a screen capture from the PSD file to show you what I’m aiming for: https://elevensixty.com/date.png

I believe I need help with the action part, I’m not sure what the right code is.

Thank you!
