    ini_set('date.timezone', 'Europe/Lisbon');
    ini_set('intl.default_locale', 'en_US');
    ini_set('intl.error_level', E_WARNING);

    $cal = new IntlGregorianCalendar(2013, 9 /* October */, 27, 1, 30);

    var_dump($cal->getRepeatedWalltimeOption()); // 0 WALLTIME_LAST

    $formatter = IntlDateFormatter::create(
        NULL,
        IntlDateFormatter::FULL,
        IntlDateFormatter::FULL,
        'UTC'
    );
    var_dump($formatter->format($cal->getTime() / 1000.));

    $cal->setRepeatedWalltimeOption(IntlCalendar::WALLTIME_FIRST);
    var_dump($cal->getRepeatedWalltimeOption()); // 1 WALLTIME_FIRST
