过程化风格

datefmt_set_timezone(IntlDateFormatter $formatter, IntlTimeZone|DateTimeZone|string|null $timezone): ?bool

Sets the timezone used for the IntlDateFormatter. object.

参数

formatter

The formatter resource.

timezone

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.

返回值

Returns null on success and false on failure.

示例 #1 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());

以上例程会输出：

NULL
    Europe/Amsterdam
IntlTimeZone
    Europe/Lisbon
DateTimeZone
    Europe/Paris
String
    Europe/Rome
IntlTimeZone Object
(
    [valid] => 1
    [id] => GMT+00:30
    [rawOffset] => 1800000
    [currentOffset] => 1800000
)
