The C library function clock(3) and the system call gettimeofday(2) measure
two quite different things.  From "man clock" on my Mandrake system:

    The clock() function returns an approximation of processor
    time used by the program.

>From "man gettimeofday":

       gettimeofday  and settimeofday can set the time as well as
       a timezone.
