如果设备日期和时间不准确，我如何获得实际的日期和时间？ [英] How can I get the actual date and time if the device date and time are inaccurate?

问题描述

我注意到如果我手动设置我的设备时间，并关闭iOS设备上的自动时间同步， [NSDate date] 会返回假设的日期和时间设备时间是正确的 - 它可能不是。

I noticed that if I set my device time manually, and turn off the automatic time sync on my iOS device, [NSDate date] returns the date and time assuming the device time is correct--which it may not be.

由于文档提到 NSDate 有某种与NTP同步，我想知道是否有任何内置方法来获得准确的日期和时间，而不必假设设备的日期和时间是正确的。

Since the docs mention that NSDate has some sort of sync with NTP, I am wondering if there is any built-in way to get the accurate date and time instead of having to assume the device date and time is correct.

推荐答案

也许 https://github.com/jbenet/ios-ntp 可以帮到你吗？它是一个可以从时间服务器获取日期和时间的库。

Perhaps https://github.com/jbenet/ios-ntp can help you? It's a library that can fetch the date and time from a time server.
