注意我的变化...

echo date("H:i:s", strtotime($row['data']) + date('Z')); // date('Z') returns timezone offset in seconds

If you have your timezone-table enabled: 如果您启用了时区表：

 mysql_query("SET time_zone='EST';");
 $data =mysql_query("SELECT DATE FROM TABLE WHERE ID = 2");
 //...etc.

If you haven't: 如果您还没有：

 mysql_query("SET time_zone='-05:00';");
 $data =mysql_query("SELECT DATE FROM TABLE WHERE ID = 2");
 //...etc.
