### 示例

示例 #1 IntlDateFormatter::getTimeZone() examples

    <?php

    $madrid = IntlDateFormatter::create(NULL, NULL, NULL, 'Europe/Madrid');
    $lisbon = IntlDateFormatter::create(NULL, NULL, NULL, 'Europe/Lisbon');

    var_dump($madrid->getTimezone());
    echo $madrid->getTimezone()->getDisplayName(
            false, IntlTimeZone::DISPLAY_GENERIC_LOCATION, "en_US"), "\n";
    echo $lisbon->getTimeZone()->getId(), "\n";
    //The id can also be retrieved with ->getTimezoneId()
    echo $lisbon->getTimeZoneId(), "\n";

以上示例会输出：

    object(IntlTimeZone)#4 (4) {
      ["valid"]=>
      bool(true)
      ["id"]=>
      string(13) "Europe/Madrid"
      ["rawOffset"]=>
      int(3600000)
      ["currentOffset"]=>
      int(7200000)
    }
    Spain Time
    Europe/Lisbon
    Europe/Lisbon
