From Symfony 2.6.

You need use @security.token_storage

use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class UserDateExtension extends \Twig_Extension
{
/**
 * @var TokenStorageInterface
 */
protected $tokenStorage;


/**
 * @param $tokenStorage TokenStorage
 */
public function __construct(TokenStorage $tokenStorage)
{
    $this->tokenStorage = $tokenStorage;
}

public function getUser()
{
    return $this->tokenStorage->getToken()->getUser();
}

public function getFilters()
{
    return array(
        'user_date' => new \Twig_Filter_Method($this, "formatUserDate"),
    );
}

public function formatUserDate($date, $format)
{
    $user = $this->getUser();
    // do stuff
}

}

And Services.yml

twig.date_extension:
    class: Acme\Twig\SpecialDateExtension
    tags:
        - { name: twig.extension }
    arguments: ["@security.token_storage"]
