我的代码上有query\\u帖子。这将显示有史以来最受欢迎的帖子。但我想展示一下过去24小时内流行的帖子。我该怎么做？

<?php query_posts(\'orderby=comment_count&order=DESC&paged=\' . get_query_var(\'paged\'));?>

<?php
/*
Template Name: try
*/
?>
<?php get_header(); ?>
    <div id="content">
                 <div class="filter_bar"><div class="fb_title">Blog Archieves</div></div>
          <div id="content_inner">
        <?php if ( ! dynamic_sidebar( \'Alert\' ) ) : ?>
            <!--Wigitized \'Alert\' for the home page -->
        <?php endif ?>

         <div id="blog_wrapper">


 <?php query_posts(\'showposts=15&orderby=comment_count&order=DESC&paged=\' . get_query_var(\'paged\'));?>
  <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

          <ul class="lp_lists">
