可以设置默认时区```date_default_timezone_set("Etc/GMT");```, 如果你是想转换时间戳，可以使用这个 function

function toTimeZone($src, $from_tz = 'America/Denver', $to_tz = 'Asia/Shanghai', $fm = 'Y-m-d
H:i:s') {
$datetime = new DateTime($src, new DateTimeZone($from_tz));
$datetime->setTimezone(new DateTimeZone($to_tz));
return $datetime->format($fm);
}

如果服务器在你手里，你可以直接设置 php.ini 里面的 date.timezone 项目。
date.timezOne= UTC

这个恐怕有点难
北京时间是政治指定的时区
格林威治时间是天文台测量的地方时
