一、获取本地时间
System.DateTime.Now
二、获取网络时间
using System;

using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using System.Net;

public FormTime()
InitializeComponent();
private void FormTime_Load(object sender, EventArgs e)
timer.Start();
Frm_Height = this.Height;
FrmHeight = this.Height;
button_Click(null, null);
// 小端存储与大端存储的转换
private uint swapEndian(ulong x)
return (uint)(((x & 0x000000ff) << 24) +

((x & 0x00ff0000) >> 8) +

// 方法1、获取NTP网络时间
public DateTime getWebTime()
// default ntp server
const string ntpServer = "ntp1.aliyun.com";
// NTP message size - 16 bytes of the digest (RFC 2030)
byte[] ntpData = new byte[48];
// Setting the Leap Indicator, Version Number and Mode values
ntpData[0] = 0x1B; // LI = 0 (no warning), VN = 3 (IPv4 only), Mode = 3 (Client Mode)
IPAddress[] addresses = Dns.GetHostEntry(ntpServer).AddressList;
foreach (var item in addresses)
Debug.WriteLine("IP:"+ item);
// The UDP port number assigned to NTP is 123
IPEndPoint ipEndPoint = new IPEndPoint(addresses[0], 123);
// NTP uses UDP
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
socket.Connect(ipEndPoint);
// Stops code hang if NTP is blocked
socket.ReceiveTimeout = 3000;
socket.Send(ntpData);
socket.Receive(ntpData);
socket.Close();
// Offset to get to the "Transmit Timestamp" field (time at which the reply
// departed the server for the client, in 64-bit timestamp format."
const byte serverReplyTime = 40;
// Get the seconds part
ulong intPart = BitConverter.ToUInt32(ntpData, serverReplyTime);
// Get the seconds fraction
ulong fractPart = BitConverter.ToUInt32(ntpData, serverReplyTime + 4);
// Convert From big-endian to little-endian
intPart = swapEndian(intPart);
fractPart = swapEndian(fractPart);
ulong milliseconds = (intPart * 1000) + ((fractPart * 1000) / 0x100000000UL);
// UTC time
DateTime webTime = (new DateTime(1900, 1, 1, 0, 0, 0, DateTimeKind.Utc)).AddMilliseconds(milliseconds);
// Local time
return webTime.ToLocalTime();
//方法2、获取ntp时间（包含润秒偏差）

//返回国际标准时间
//只使用的TimerServer的IP地址，未使用域名
