在WIN2000下如何用C#改变系统日期时间

1、调用控制面板选项：timedate.cpl
2、使用WMI进行改变：

using System;
 using System.Runtime.InteropServices;namespace ConsoleApplication20
 {
   [StructLayout(LayoutKind.Sequential)]
   public struct SYSTEMTIME
   {
     public ushort wYear;
     public ushort wMonth;
     public ushort wDayOfWeek;
     public ushort wDay;
     public ushort wHour;
     public ushort wMinute;
     public ushort wSecond;
     public ushort wMilliseconds;    public DateTime ToDateTime()
     {
       return new DateTime(wYear, wMonth, wDay, wHour, wMinute, wSecond,
 wMilliseconds);
     }
   }  class Win32API
   {
     [DllImport("Kernel32.dll")]
     public static extern bool SetSystemTime(ref SYSTEMTIME st);
     [DllImport("Kernel32.dll")]
     public static extern void GetSystemTime(out SYSTEMTIME st);
   }  class Class1
   {
     [STAThread]
     static void Main(string[] args)
     {
       SYSTEMTIME st;
       Win32API.GetSystemTime(out st); // gets current time
       Console.WriteLine( st.ToDateTime().ToLocalTime().ToString() );
       st.wMinute++; // Adjust minutes
       if (!Win32API.SetSystemTime(ref st)) // sets system time
         Console.WriteLine("An error occured setting the system time");
       Win32API.GetSystemTime(out st); // gets current time
       Console.WriteLine( st.ToDateTime().ToLocalTime().ToString() );
       Console.ReadLine();
     }
   }
 }
