System Call implementation

I am trying to extend the system call for my_time.

I am extending timekeeping.c for it. But its giving me random time.

struct timeval tv;

// get the current time
do_gettimeofday(&tv);
current_time->tv_sec=tv.tv_sec;
current_time->tv_nsec=tv.tv_usec*1000;

return( current_time->tv_nsec);

I figured it out. Actually time is nanoseconds so its not random. Its just for each seconds its showing high deviation
