calThe IntlCalendar resource.
timeZoneThe new timezone to be used by this calendar. It can be specified in the following ways:

the ini setting date.timezone or
through the function date_default_timezone_set() and as
returned by date_default_timezone_get().
An IntlTimeZone, which will be used directly.
A DateTimeZone. Its identifier will be extracted and an ICU timezone object will be created; the timezone will be backed by ICU?s database, not PHP?s.
A string, which should be a valid ICU timezone identifier. See IntlTimeZone::createTimeZoneIDEnumeration(). Raw offsets such as "GMT+08:30" are also accepted.
Returns TRUE on success and FALSE on failure.

<?php
ini_set('date.timezone', 'Europe/Lisbon');
ini_set('intl.default_locale', 'es_ES');
$cal = new IntlGregorianCalendar(2013, 5 /* May */, 1, 12, 0, 0);
echo IntlDateFormatter::formatObject($cal, IntlDateFormatter::FULL), "\n";
echo "(instant {$cal->getTime()})\n";
$cal->setTimeZone(IntlTimeZone::getGMT());
echo IntlDateFormatter::formatObject($cal, IntlDateFormatter::FULL), "\n";
echo "(instant {$cal->getTime()})\n";
$cal->setTimeZone('GMT+03:33');
