Symfony / PHP DateTimeZone缺少时区

Question

I've got a Symfony API that is storing the users timezone as part of the login process. However, it seems certain timezones causes an error. Using 'America/Buenos_Aires' as an example value being sent, the following code causes 500 error to be thrown.

$validator->validate($request->request, new Assert\Collection([
        'username' => new AppAssert\Chain([
            new Assert\Type('string'),
            new Assert\NotBlank(),
        ]),
        'password' => new AppAssert\Chain([
            new Assert\Type('string'),
            new Assert\NotBlank(),
        ]),
        'timezone' => new AppAssert\Chain([
            new Assert\Type('string'),
            new Assert\NotIdenticalTo(''),
            new Assert\Choice([
                'choices' => \DateTimeZone::listIdentifiers(),
                'strict' => true,
            ]),
        ]),
    ]));

Looking at this post https://bugs.php.net/bug.php?id=70816 it states to use DateTimeZone::ALL_WITH_BC, which I've tried

'choices' => \DateTimeZone::listIdentifiers(DateTimeZone::ALL_WITH_BC),

but still to no avial.

The client is using Moment JS which seems to sometimes return America/Argentina/Buenos_Aires and sometimes America/Buenos_Aires but America/Argentina/Buenos_Aires works fine.

I finally figured it out, I was missing \ off DateTimeZone::ALL_WITH_BC

Full correct code

 'timezone' => new AppAssert\Chain([
            new Assert\Type('string'),
            new Assert\NotIdenticalTo(''),
            new Assert\Choice([
                'choices' => \DateTimeZone::listIdentifiers(\DateTimeZone::ALL_WITH_BC),
                'strict' => true,
            ]),
        ]),
