PHP: Timezone

$tz = "2022-11-03T10:16:36.000Z";
$ts = strtotime($tz);
echo $ts."\n\n";       // this will output 1667470596

$d = new DateTime();
$d->setTimestamp($ts);
echo $d->format("Y-m-d H:m:s")."\n\n";          // this will output 2022-11-03 10:11:36
echo $d->getTimezone()->getName()."\n\n";       // this will output UTC

$d->setTimezone(new DateTimeZone("Asia/Jakarta"));
echo $d->format("Y-m-d H:m:s")."\n\n";          // this will output 2022-11-03 17:11:36
