Custom timezone resolver

For add custom user timezone resolver you need create service and implement ResolverInterface. Example service for get timezone for authorized user:

namespace Acme\Bundle\DemoBundle\Date\TimeZone\Resolver;

use Acme\Bundle\DemoBundle\Entity\User;
use GpsLab\Bundle\DateBundle\TimeZone\Resolver\ResolverInterface;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class UserResolver implements ResolverInterface
{
    protected $storage;

    public function __construct(TokenStorageInterface $storage)
    {
        $this->storage = $storage;
    }

    public function getUserTimeZone()
    {
        // get timezone from user entity
        if (
            ($token = $this->storage->getToken()) &&
            ($user = $token->getUser()) &&
            $user instanceof User &&
            $user->getTimezone()
        ) {
            return new \DateTimeZone($user->getTimezone());
        }

        return null;
    }
}
