Description:
------------
For some timezones IntlDateFormatter returns null instead of instance.

Test script:

foreach (\DateTimeZone::listIdentifiers() as $timezone) {
    $formatter = new \IntlDateFormatter(
        'en_US',
        1,
        1,
        $timezone,
        null,
        null
    );
    if (null === $formatter) {
        echo $timezone . PHP_EOL;
    }
}

Expected result:

Hi,

The issue of the IntlDateFormatter returning null will be fixed with the release of PHP 7; the behaviour was deliberate before, but was changed by an RFC https://wiki.php.net/rfc/internal_constructor_behaviour

Just to note, your code example below will now throw an IntlException where it was before returning null from the constructor. The root cause of it failing to make the IntlDateFormatter is, I presume, that the Intl library is not aware of those timezones, as that library gets its data from a different location than the DateTime library.

If you think PHP should be aware of those timezones, please can you check that the ICU library on your system is aware for them?

cheers
Dan
