Changing windows system clock

[PlasmaZero]

I'm looking for a way to change the system clock on WinXP(i.e. simply alter the hours/min/sec), but I haven't been able to find anything. Does anyone know of either a class or just some way to do this?
Thanks

BOOL SetSystemTime(CONST SYSTEMTIME *lpSystem);
