我怎样才能获得＆QUOT;联播网中;时间（从＆QUOT;自动＆QUOT;设置称为QUOT;使用网络提供的值＆QUOT;），没有时间在手机上？
我想在我的应用程序，以找到一种方法来同步的日期和时间的东西由外部源给出。
I would like in my application to find a way to synch the date and time with something given by an external source.
我不希望使用手机的时间，因为我可能会得到各地真实的时间也许5分钟的差别。 5分钟额外的或更少= 10分钟！
I don't want to use the phone time because I might get a difference of maybe 5 minutes around real time. and 5 minutes extra or less = 10 minutes!
我已经听说了GPS卫星或网络天线时间信息。
I have heard about time information in the GPS satellites or in Network antennas.
我曾尝试与System.getCurrentTime，但我得到的器件的电流，所以，如果我的设备设置提前5分钟，就显示错误的时间。
I have tried with System.getCurrentTime but i get the current the of the device, so, if my device is set up 5 minutes earlier, it display the wrong time.
修改
要作一个简短的问题：我怎么能得到这个时间
To make a short question: how can I get this time?
我不知道，但发现这个问题有意思。所以，我挖在Android code ...感谢开源：）
I didn't know, but found the question interesting. So I dug in the android code... Thanks open-source :)
您显示屏幕为 DateTimeSettings 。勾选使用网络提供的值相关联的共享preference 字符串KEY_AUTO_TIME =auto_time; ，也为 Settings.System .AUTO_TIME
The screen you show is DateTimeSettings. The checkbox "Use network-provided values" is associated to the shared preference String KEY_AUTO_TIME = "auto_time"; and also to Settings.System.AUTO_TIME
这是设置观察观察到的名为 mAutoTimeObserver 在2个网络 ServiceStateTracker S：
GsmServiceStateTracker 和 CdmaServiceStateTracker 。
This settings is observed by an observed called mAutoTimeObserver in the 2 network ServiceStateTrackers:
GsmServiceStateTracker and CdmaServiceStateTracker.
两种实现调用一个方法称为 revertToNitz（）当设置为真。
显然 NITZ 是NTP在载体世界等效
Both implementations call a method called revertToNitz() when the settings becomes true.
Apparently NITZ is the equivalent of NTP in the carrier world.
底线：您可以将时间设定为revertToNitz为提供的载体感谢值（）。
不幸的是，我还没有找到一种机制来获取网络时间。
如果你真的需要做到这一点，我很害怕，你必须复制这些 ServiceStateTracker 取值实现，搭上由框架（我想）提出的意图，并添加getter到 mSavedTime 。
Bottom line: You can set the time to the value provided by the carrier thanks to revertToNitz().
Unfortunately, I haven't found a mechanism to get the network time.
If you really need to do this, I'm afraid, you'll have to copy these ServiceStateTrackers implementations, catch the intent raised by the framework (I suppose), and add a getter to mSavedTime.
