change server timezone into specific timezone using php

Question

In phpmyadmin under date_time row the time value updated like this

2015-02-22 00:40:54

Well, This code is working fine for a single value

$timezone = new DateTimeZone('America/Vancouver');

$date = new DateTime(date('m/d/Y h:i:s a', time()));
$date->setTimeZone($timezone);
$msg_time = $date->format('h:i A M d'); // current time

But what if I get a row from db like this

$msg_time = date('h:i A M d',strtotime($row["date_time"])); 

again it is showing the server time for "date" so how to fix this, not need to show the client's time using js but just want to show the time in a specific timezone instead of server timezone.

您始终可以获取时区之间的GMT偏移量并进行一些数学运算...
