Could you be a little more specific please cause I don't understand?

>getnstimeofday uses the syste, cllock that can be retrieved using
>/sys/devices/system/clocksource/clocksource0/current_clocksource

The problem in my case is that when I execute the above, I get:
cat: can't open
'/sys/devices/system/clocksource/clocksource0/current_clocksource': No such
file or directory
In general, my /sys directory is empty. This file should exist to my
filesystem prior to kernel execution or should it be created by the kernel
when it starts executing; but for some reason it is not being created in my
case?

Thanks.
