Dear,

Does someone knows how to alter the hardware time under linux, from C(++) ?

I use the stime function, but this seems to change only the time of the operating system, without changing the real time clock.

Thanks,
Gregory

The hardware clock would normally be altered using /sbin/hwclock (--systohc I think).  See "man hwclock" for details.

As for calling it from your program,
(A) just call hwclock
(B) hwclock should only be executable by root (of course, any other method to set system clock should also only be usable by root :-).  If this causes problems with your program, redesign your program.  Just out of interest, why do you want to set it programatically?  Sounds like A Bad Idea.
