            $this->errorCode = self::ERROR_PASSWORD_INVALID;
        } else {
            $this->_id = $user->id;
            if (null === $user->last_login_time) {
                $lastLogin = time();

                $lastLogin = strtotime($user->last_login_time);
            }
            $this->setState('last_login_time', $lastLogin);
            [color=Red][size=6]$this->setState('email', $user->email);[/size][/color]
