Was a post posted within last 12 hours?

Hi everyone,

Was wondering if I could get a bit of help. Have looked at the forums but all related solutions I find mention variables such as $post, which I don’t have in my loop below I don’t think? What I want to do is check if each post in the loop was posted within the last 12 hours, and if so display an image (it’s just a small icon to alert the user that it’s a recent post). The simplified code for my loop is:

<?php while (have_posts()) : the_post(); ?>

<div class="post">

<h2 id="post-<?php the_ID(); ?>"><a>"<?php the_title();</a></h2>

<small><?php the_time('F jS') ?></small>

<div class="entry">
<?php the_content('Read more �'); ?>
</div>

</div>

<?php endwhile; ?>

Would really appreciate any help anyone can give me – basically, if someone can tell me what the php IF statement is to check if it was posted in the last 12 hours, I know how to do the if… else and insert the image.

Thanks in advance,

Guy
