    var_dump($cal->getRepeatedWalltimeOption()); // 0 WALLTIME_LAST
    $formatter = IntlDateFormatter::create(
        NULL,

        IntlDateFormatter::FULL,
        'UTC'
    );
    var_dump($formatter->format($cal->getTime() / 1000.));
    $cal->setRepeatedWalltimeOption(IntlCalendar::WALLTIME_FIRST);
    var_dump($cal->getRepeatedWalltimeOption()); // 1 WALLTIME_FIRST
