Special Class for Today’s Post

Is there a php code that is used when you would like to use a special class for posts that were written today?

something like:

<?php $today = date('F jS, Y'); ?>
<div class="entry<?php if ($today = the_time('F jS, Y')) { ?>today<? }else{ ?><?php }?>">

Doing this simply echoes the date in the template. It’s driving me crazy.

Any help would be really appreciated. ??
