楼主的程序我没试过，不过设置系统的时间，我试了单单使用SetSystemTime
没有效果，不能修改，要先GetSystemTime，在调用SetSystemTime才可以.
public class Win32API
{
[ DllImport( "Kernel32.dll" )]
public static extern bool SetSystemTime([In,
MarshalAs(UnmanagedType.LPStruct)]SYSTEMTIME lpSystemTime);
[DllImport("kernel32.dll")]
public static extern void GetSystemTime([Out,
MarshalAs(UnmanagedType.LPStruct)]SYSTEMTIME lpSystemTime);
}
...
SYSTEMTIME s=new SYSTEMTIME();
Win32API.GetSystemTime(s);
s.wYear=1999;
s.wMonth=10;
s.wHour=10;
Win32API.SetSystemTime(s);
或许我写的不对，不知楼主可以设置成功吗？

To ZRWeng:
呵呵，我们也算是熟人了，你的写法应该是对的。但我那样写确实也可以设置成功。你可以到这里下载这个程序的EXE：
http://www.donghe-hk.com/yyh/csharp/bin/CheckTime.rar

本人编写了一个关于公安局对法轮功及间谍等犯罪人员的管理系统！C#加SQL2000！有意者可以与我联系啊！gaozhifeng@mail.china.com

可以给个演示看看吗？
boby_hai@hotmail.com

呵呵，看错了！

bill.robin@263.net

intrawen@tom.com 我也要。谢了

好大的砖头 你老人家能不能写简练一点

这又能说明什么！[?]

我也要！
resun_shaoqing@163.com谢谢

接受答案了.
