通过WPF客户端应用程序更改系统时间的策略

Question

I found good advice how to change system time here .

It's ok... But what is the best strategy to change system local time for the WPF client application then?

For example my application periodically gets some data from server and I can pass the server time with it.

Or may be is better to use additional thread to ask server about the server time and change local system time always...

So I don't know which approach is better...

Thanks for any clue.

It is better not to do it at all - it requires admin privileges to change system time, so your program will have to run as admin (may be acceptable in your case, but normally not a good idea).

It is also requires some effort to correctly adjust for network latency when setting time. Please check out how it is normally done, ie starting with NTP - Network Time Protocol .

One option is to configure windows to check time more often itself instead doing it by hand as it already implements the functionality.
