Show last edit time into Wordpress

If you would like to show when the article was last edited you need to put the following code to the theme that you use.

Posted on <?php the_time('F jS, Y') ?>
<?php $u_time = get_the_time('U');
$u_modified_time = get_the_modified_time('U');
if ($u_modified_time != $u_time) {
echo "and last modified on ";
the_modified_time('F jS, Y');</div>
<echo ". "; } ?>
Posted on <?php the_time('F jS, Y') ?><?php $u_time = get_the_time('U');$u_modified_time = get_the_modified_time('U');if ($u_modified_time != $u_time) {echo "and last modified on ";the_modified_time('F jS, Y');echo ". "; } ?>
