关于jwt续签的一点小疑问

tymon/jwt-auth这个组件的源码,发现在刷新token的时候,新token的签发时间还是用的原token的。比如我把refresh_ttl设置成一小时,30分钟刷新一次token,那一小时之后就必须重新登录了。

protected function buildRefreshClaims(Payload $payload)
    {
        // Get the claims to be persisted from the payload
        $persistentClaims = collect($payload->toArray())
            ->only($this->persistentClaims)
            ->toArray();

        // persist the relevant claims
        return array_merge(
            $this->customClaims,
            $persistentClaims,
            [
                'sub' => $payload['sub'],
                'iat' => $payload['iat'],
            ]
        );
    }
public function validateRefresh($refreshTTL)
    {
        if ($this->isPast($this->getValue() + $refreshTTL * 60)) {
            throw new TokenExpiredException('Token has expired and can no longer be refreshed');
        }
    }
