I don't know about `date -s`; it's not in my `man date`.

But, I see a "-a adjustment" option:  "On BSD-based systems,
the adjustment is made by changing the rate at which time advances".
This can adjust the time forward or backward the given number of seconds.  
It sounds good.  Does it apply to Linux?

If you're talking about changing the hardware clock, I don't know
what effect that might have, if any.
