Changing the time zone in PHP is not working

php set timezone

date_default_timezone_set not working
php change server time
date_default_timezone_set php utc

zabbix time zones
php set timezone pst

My hosting company set the default time zone in my php.ini to America/Chicago. I confirmed the time zone by checking phpinfo() and echoing date_default_timezone_get() in my PHP code.

However, I tested changing the time zone in my PHP code but had no luck.

Firstly, I tested:

echo (new DateTime())->getTimestamp();
echo '<br>';
date_default_timezone_set('UTC');
echo (new DateTime())->getTimestamp();

And the two echoed timestamps were the same.

Then, I tested:

echo (new DateTime())->getTimestamp();
echo '<br>';
$now = new DateTime();
$now->setTimezone(new DateTimeZone('UTC'));
echo $now->getTimestamp();

And the two echoed timestamps were still the same.

getTimestamp returns a UNIX Epoch timestamp. UNIX timestamps are always the same all over the world. Time zones only affect human readable time, e.g. when you do $now->format('H:i:s').
