Description:
------------
<?php


$dt = new DateTime("1970-01-01 ".date("H:i:s"));
$dt->setTimezone(new DateTimeZone('UTC'));
echo $dt->format('r');
echo "\n";
$seconds = (int)$dt->getTimestamp();
echo date("H:i:s",$seconds);
echo "\n";

?>

even if i am setting the timezone to UTC, it is taking only the server time.

Expected result:
----------------
It should take the UTC time zone.

Actual result:
--------------
It should take the UTC time zone.

That is not how timezones and Unix timestamps work.

You created a date and time according to the server timezone. Changing the timezone from there only affects the string representation of it - the timestamp is the same. Getting that timestamp and formatting it according to the server timezone will get you right back to where you started.

$dt = new DateTime("1970-01-01 ".date("H:i:s"), new DateTimeZone('UTC'));
        $seconds = (int)$dt->getTimestamp();
        echo date("H:i:s",$seconds);

This snippet works fine in earlier versions of php i.e it is not taking the server time zone. but when i updated to the specified version.
it is always taking the server time and ignoring the timezone specified.

You know the default timezone in PHP is UTC, right?

No..its in IST time zone.

What does date_default_timezone_get() return?

<?php

echo date_default_timezone_get();
?>
