问题是今天的美元正在从数据库中提取GMT；我需要将GMT偏移-6小时；找不到这样偏移量的查询。

<?php
   $paged = ( get_query_var(\'paged\') ) ? get_query_var(\'paged\') : 1;
   $today = date(\'Y-m-d\');
   query_posts(array(
   \'post_type\' => \'performance\', 
   \'posts_per_page\' => 4, 
   \'caller_get_posts\' => 4, 
   \'paged\' => $paged,
   \'meta_key\' => \'order-date\',
   \'orderby\' => \'meta_value\',
   \'order\' => \'ASC\',
       \'meta_query\' => array(
           array(
             \'key\' => \'order-date\',
             \'meta-value\' => $value,
             \'value\' => $today,
             \'compare\' => \'>=\',
             \'type\' => \'CHAR\'
         )
      )
    ));
  if (have_posts()) :
  while (have_posts()) : the_post();
?>
