C # From the network acquisition time update this machine time

Due to the problem of the main board, it is lost time, so I think a method is to get the latest time from the Internet, so I don't need to go to the time, the network is all, the time can automatically correct.

When calling: resetLocalTimeFromNetwork Objresettime = New ResetLocalTimeFromNetWork (Strremoteip, StrremotEport, Strtimezone);
