convert timezone to another timezone

I want to convert the date I fetched from the database, which is generated via CURRENT_TIMESTAMP and stored in a timestamp column type, from GMT+8 to GMT+1.

$time = "2012-11-07 15:05:26"; // fetch from database
$date = new DateTime($time, new DateTimeZone('Europe/Berlin'));
echo $date->format('Y-m-d H:i:s');

However this will yield an output of "2012-11-07 15:05:26", which I'm pretty sure is wrong.

What could be I'm missing in here?

First, you need to instantiate the datetime object with the original timezone. Then, after the datetime object is instantiated, adjust the timezone with DateTime::setTimezone().

See this code, where I've used Asia/Hong_Kong as an example GMT+8 timezone:

$time = "2012-11-07 15:05:26"; // fetch from database
$date = new DateTime($time,new DateTimeZone('Asia/Hong_Kong'));
$date->setTimezone(new DateTimeZone('Europe/Berlin'));
echo $date->format('Y-m-d H:i:s'); // yields 2012-11-07 08:05:26

If all the original dates are always consistently meant as GMT+8, and your PHP application is set to use GMT+8 as well (set with date_default_timezone_set(), for instance), there's no need to pass the initial DateTimeZone object, as newly created DateTime objects will automatically be created with that timezone.

Maybe this could help. Just integrate it in your query to simplified your coding:

SELECT CONVERT_TZ('2012-11-07 15:05:26','+08:00','+01:00');

You can have more info here, regarding timezones you want to use. And here for more understanding

Check this : 

<?php

$time = "2012-11-07 15:05:26"; // fetch from database

$tz_object = new DateTimeZone('Europe/Berlin'); 
$datetime = new DateTime($time); 
$datetime->setTimezone($tz_object); 
echo $datetime->format('Y-m-d H:i:s');
//output 2012-11-07 10:35:26
?>
