自动续订订阅错误时间响应沙盒模式

我目前正在尝试进行本地收据验证并进行测试。但是从苹果收据响应中，我得到了错误的时间相关响应，因此目前我很难测试应用程序。

以下是日志信息：

这是我用于收据验证的源代码：

 public void CheckIfSubscriptionIsActive(bool validateReceipt)
{
    ConfigurationBuilder builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());

    IAppleConfiguration appleConfig = builder.Configure<IAppleConfiguration>();
    bool isSubscriptionRunning = false;

    if (!string.IsNullOrEmpty(appleConfig.appReceipt))
    {
        if (validateReceipt)
        {
            // local receipt verification
            var receiptData = System.Convert.FromBase64String(appleConfig.appReceipt);
            AppleReceipt receipt = new AppleValidator(AppleTangle.Data()).Validate(receiptData);
            foreach (AppleInAppPurchaseReceipt productReceipt in receipt.inAppPurchaseReceipts)
            {

                Debug.Log("# server date: " + GameManager.Instance.ServerDate + " expire date: " + productReceipt.subscriptionExpirationDate);
                int result = DateTime.Compare(GameManager.Instance.ServerDate, productReceipt.subscriptionExpirationDate);
                if (result <= 0)
                {
                    isSubscriptionRunning = true;
                    Debug.Log(" === ==== === Subscription Running: curr date: " + GameManager.Instance.ServerDate + " expire date: " + productReceipt.subscriptionExpirationDate);
                }

                //Debug.Log("PRODUCTID: " + productReceipt.productID);
                //Debug.Log("PURCHASE DATE: " + productReceipt.purchaseDate);
                //Debug.Log("EXPIRATION DATE: " + productReceipt.subscriptionExpirationDate);
                //Debug.Log("CANCELDATE DATE: " + productReceipt.cancellationDate);
            }

            if (isSubscriptionRunning)
                SubscriptionActivated();

            // hide loading...
            showLoader = false;
            Camera.main.SendMessage("ActivateLoadingDialog", false, SendMessageOptions.DontRequireReceiver);

        }
        else
        {
            // server side receipt vecification
            appReceipt = appleConfig.appReceipt;
            StartCoroutine(CheckSubscriptionStatusServerSideVerification());
        }
    }
}

通常每周订阅有 3 分钟的持续时间，所以如果我没有得到确切的时间，那么我该如何进行适当的测试！！

In above image, I have mention both times, my local time is 15:01:04 and apple receipt response time is 09:37:18. Using local device receipt validation at present I can't able to test the work. so what way exist for me for testing??
