如何使用PEAR :: Date获取DST的时区小时偏移量和帐户？

I am trying to get the offset hours from UTC, given a summer date. My system time is set to America/Los_Angeles.

考虑到夏天,我试图从UTC获得偏移小时数。我的系统时间设置为America / Los_Angeles。

I have the following:

我有以下内容:

require_once("Date.php");

$dateTZ = new Date_TimeZone('America/Los_Angeles');

echo $dateTZ->getOffset(new Date('2009-07-01 12:00:00'))/1000/60/60;

This prints '-8'; shouldn't it show '-7'?

这打印'-8';不应该显示'-7'?

echo $dateTZ->getOffset(new Date())/1000/60/60;

also prints '-8'.

还打印'-8'。

What am I doing wrong?

我究竟做错了什么?

Does Date::inDaylightTime() help you? Date::getTZOffset claims to include daylight savings offset.

Date :: inDaylightTime()会帮助你吗? Date :: getTZOffset声称包括夏令时偏移。
