To the following time and date format:
到以下时间和日期格式：
Monday March 28 2011 4:48:02 PM
I am using the following PHP code to accomplish this, but I want to convert all time zones to PST/PDT. I looked at the PHP manual and saw this date_default_timezone_set()but I am not sure how to implement that into the code I have below.
我使用以下 PHP 代码来完成此操作，但我想将所有时区转换为 PST/PDT。我查看了 PHP 手册并看到了这一点，date_default_timezone_set()但我不确定如何将其实现到我下面的代码中。
$date = $messages[0]->CreationTime;
echo date('l F j Y g:i:s A I', strtotime($date))

I would not use date_default_timezone_setfor general TZ conversions. (To clarify... if this is for display purposes, script wide, then using the default timezone is a reasonable thing to do.)
我不会date_default_timezone_set用于一般的 TZ 转换。（澄清......如果这是为了显示目的，脚本范围，那么使用默认时区是合理的做法。）
Instead, I would use something like:
相反，我会使用类似的东西：
$tz = new DateTimeZone('America/Los_Angeles');
$date = new DateTime('Thu, 31 Mar 2011 02:05:59 GMT');
$date->setTimezone($tz);
echo $date->format('l F j Y g:i:s A I')."\n";
