>Description:
SUSv2(http://opengroup.org/onlinepubs/007908799/xsh/timer_settime.html) says

>The members of ovalue are subject to the resolution of the timer, and they are the 
>same values that would be returned by a timer_gettime() call at that point in time. 

and 

>The timer_gettime() function stores the amount of time until the specified timer,
> timerid, expires and the reload value of the timer into the space pointed to by
> the value argument.
>(snip) 
> This value is returned as the interval until timer expiration, even if the timer
> was armed with absolute time.

but our timer_settime(2) always sets absolute time into ovalue when the timer was created as CLOCK_REALTIME.(CLOCK_VIRTUAL returns relative time correctly.)
