推荐答案

简单的答案是否".如果您无法访问NTP服务器或外部服务器来请求必须依靠设备的时间，那么就不可能这样做.尽管唯一的时间参考点是设备上设置的时间，但是您可以跟踪自打开应用程序以来经过了多少时间.

The simple answer is no. If you can't access an NTP server or an external server to request the time you have to rely on the device, it would be impossible to do otherwise. You can track how much time has passed since your app has opened although the only reference point for time is that set on the device.

重要的问题是，为什么准确的日期对您的应用至关重要?

The important question is why an accurate date is crucial to your app?
