A DateTimeZone. Its identifier will be extracted and an ICU timezone object will be created; the timezone will be backed by ICUʼs database, not PHPʼs.

<?php

$formatter = IntlDateFormatter::create(NULL, NULL, NULL, "UTC");
$formatter->setTimeZone(NULL);
echo "NULL\n ", $formatter->getTimeZone()->getId(), "\n";
$formatter->setTimeZone(IntlTimeZone::createTimeZone('Europe/Lisbon'));
echo "IntlTimeZone\n ", $formatter->getTimeZone()->getId(), "\n";
$formatter->setTimeZone(new DateTimeZone('Europe/Paris'));
echo "DateTimeZone\n ", $formatter->getTimeZone()->getId(), "\n";
$formatter->setTimeZone('Europe/Rome');
echo "String\n ", $formatter->getTimeZone()->getId(), "\n";
$formatter->setTimeZone('GMT+00:30');
print_r($formatter->getTimeZone());
