Question

I am unable to set timezone for my DateTime objects.
Here is my code :

$dt = DateTime::createFromFormat('U',time(),new DateTimeZone('Asia/Kolkata'));
print_r($dt->getTimeZone());

Here is the output :

DateTimeZone Object
(
)

I also tried putting these lines at the top (one at a time) – without any success:

date_default_timezone_set('Asia/Calcutta');
ini_set('date.timezone', 'Asia/Calcutta');
date_default_timezone_set('Asia/Kolkata');
ini_set('date.timezone', 'Asia/Kolkata');

Answer 1

This is because you specified UNIX timestamp in the parameter. See what php manual says.

The timezone parameter and the current timezone are ignored when the time parameter either contains a UNIX timestamp (e.g. 946684800) or specifies a timezone (e.g. 2010-01-28T15:00:00+02:00).

What you are trying to do can be easily done by,

$dt = new DateTime("now", new DateTimeZone('Asia/Kolkata'));

If you have a variable that contains UNIX timestamp, first create a DateTime object with it. Then set the new TimeZone.

$dt = new DateTime("@$timestamp");
$dt->setTimezone( new DateTimeZone('Asia/Kolkata'));
