Modificar la fecha de los comentarios

[ManuelAlejandro]

Saludos de nuevo, me enfrento a otro apasionante dilema en el sistema WordPress, y es que tengo unos comentarios con la siguiente estructura en la fecha:

21 febrero, 2011 a las 10:18

Y me gustaría dejar el día, el mes y el año, y eliminar el a las x hora.

El código de comments.php es este pero no logro encontrar el trozo correspondiente:

Código:

<?php

// Do not delete these lines
	if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
		die ('Please do not load this page directly. Thanks!');

	if ( post_password_required() ) { ?>

<p class="nocomments">Password protected.</p>
<?php
		return;
	}
?>
<!-- You can start editing here. -->
<div class="comments-box"> <a name="comments" id="comments"></a>
  <?php if ( have_comments() ) : ?>
  <h2>
    <?php comments_number('', '1 Opini&oacute;n', '% Opiniones' );?>
  </h2>
  <ol class="commentlist">
    <?php wp_list_comments('type=comment&avatar_size=48'); ?>
  </ol>
  <div class="pagenavi">
    <div class="nextprev left">
      <?php previous_comments_link() ?>
    </div>
    <div class=" nextprev right">
      <?php next_comments_link() ?>
    </div>
    <div class="clear"></div>
  </div>
  <?php else : // this is displayed if there are no comments so far ?>
  <?php if ('open' == $post->comment_status) : ?>
  <!-- If comments are open, but there are no comments. -->
  <?php else : // comments are closed ?>
  <!-- If comments are closed. -->
  <?php endif; ?>
  <?php endif; ?>
  <?php if ('open' == $post->comment_status) : ?>
  <div id="respond">
    <h2>Tu opini&oacute;n</h2>
    <div class="cancel-comment-reply"> <small>
      <?php cancel_comment_reply_link(); ?>
      </small> </div>
    <?php if ( get_option('comment_registration') && !$user_ID ) : ?>
    <p><?php print 'You must be'; ?> <a href="<?php echo get_option('siteurl'); ?>/wp-login.php?redirect_to=<?php echo urlencode(get_permalink()); ?>"><?php print 'Logged in'; ?></a> <?php print 'to post comment'; ?>.</p>
    <?php else : ?>
    <form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="commentform">
      <?php if ( $user_ID ) : ?>
      <p><?php print 'Logged as'; ?> <a href="<?php echo get_option('siteurl'); ?>/wp-admin/profile.php"><?php echo $user_identity; ?></a>. <a href="<?php echo wp_logout_url(get_permalink()); ?>" title="Log out of this account"><?php print 'Log out'; ?> &raquo;</a></p>
      <?php else : ?>
      <p>

        <label for="author"><small>
          <?php if ($req) echo "(requerido)"; ?>
          </small></label>
      </p>
      <p>
        <input class="email" type="text" value="tu email..." onclick="this.value='';" name="email" id="email" size="22" tabindex="2"/>
        <label for="email"><small>(no ser&aacute; publicado)

      <?php endif; ?>
      <!--<p><small><strong>XHTML:</strong> You can use these tags: <code><?php echo allowed_tags(); ?></code></small></p>-->
      <p>

        <?php comment_id_fields(); ?>
      </p>
      <?php do_action('comment_form', $post->ID); ?>
    </form>
    <?php endif; // If registration required and not logged in ?>
  </div>
  <?php endif; // if you delete this the sky will fall on your head ?>
</div>
