date_default_timezone_set('PRC');
$newdate = time();
$updated_date = get_the_modified_time('Y-m-d H:i:s');
$updatetime = strtotime($updated_date);
$custom_content = '';
if ($newdate > $updatetime + 86400) {
$custom_content = '<div class="article-update-tips"><p class="update-ts">文章最后更新时间：<span1>' . $updated_date . '</span1></p></div>';
