Please make new functions prefixed with timer_ and get rid of that old
interface completely. It's horrible.
 
timer_init()
timer_start(timer, ms, abs)
timer_start_on(timer, ms, abs, cpu)
timer_cancel(timer, sync)

Is all what's required to make up a new milliseconds based interface.

We really do not need all that mod/restart/ whatever variants. Where is the
point of those?

Thanks,
