在windows 7上使用c#设置系统时间

[StructLayout(LayoutKind.Sequential)]
public struct SYSTEMTIME 
{
public short wYear;
public short wMonth;
public short wDayOfWeek;
public short wDay;
public short wHour;
public short wMinute;
public short wSecond;
public short wMilliseconds;
}
[DllImport("kernel32.dll", SetLastError=true)]
public static extern bool SetSystemTime( [In] ref SYSTEMTIME st );
SYSTEMTIME st = new SYSTEMTIME();
st.wYear = 2003; // must be short 
st.wMonth = 5; 
st.wDay = 22;
st.wHour = 0;
st.wMinute = 0;
st.wSecond = 0;
SetSystemTime(ref st);

我不确定是否有一个。net的方式这样做，但有一个函数在Win32称为SetLocalTime。http://msdn.microsoft.com/en-us/library/ms724936 (VS.85) . aspx注意，用户可能需要提升权限才能执行此操作。
