基本过程如下： 1. 利用ntp服务器获取网络时间     QUdpSocket udp_sock;     udp_sock.connectToHost("time.windows.com",123); 2. 阻塞等待连接成功     if(udp_sock.waitForConnected(60000))     {         ...     } 3. 发送时间请求         udp_sock.write(time_req);         udp_sock.flush(); 4. 阻塞等待消息返回         if(udp_sock.waitForReadyRead(120000))         {             ...         } 说明：此过程等待时间可能较长，出现连接失败的情况也比较常见。
