Procedural style

boolean datefmt_set_timezone ( mixed $zone )

Sets the timezone that will be used when formatting dates or times with this object.

Parameters:

zone

The timezone to use for this formatter. This can be specified in the following forms:

NULL, in which case the default timezone will be used, as specified in 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 ICUʼs database, not PHPʼs.
A string, which should be a valid ICU timezone identifier. See IntlTimeZone::createTimeZoneIDEnumeration(). Raw offsets such as "GMT+08:30" are also accepted.

Returns:

Returns TRUE on success and FALSE on failure.

IntlDateFormatter::setTimeZone() examples

<?php
ini_set('date.timezone', 'Europe/Amsterdam');

$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());

The above example will output:

NULL
    Europe/Amsterdam
IntlTimeZone
    Europe/Lisbon
DateTimeZone
    Europe/Paris
String
    Europe/Rome
IntlTimeZone Object
