//从本机获取服务器时间
SNTPTimeClient client = new SNTPTimeClient("10.0.5.126", "123");///////填写你想要的获取时间的主机的IP和端口;
client.Connect();
DateTime getEd = client.ReceiveTimestamp;//获取指定IP的系统时间
SystemTime st = new SystemTime
{
wDay = (ushort)getEd.Day,
wDayOfWeek = (ushort)getEd.DayOfWeek,
wHour = (ushort)getEd.Hour,
wMiliseconds = (ushort)getEd.Millisecond,
wMinute = (ushort)getEd.Minute,
wMonth = (ushort)getEd.Month,
wSecond = (ushort)getEd.Second,
wYear = (ushort)getEd.Year
};
SNTPTimeClient.SetLocalTime(st);//设置本地时间;
局域网内，用C#实现本地电脑获取服务器系统时间，并更新到本地电脑
