Hi Philip,

The clock function returns consumed CPU time by the process, not the
real time. And the documentation says about the tick unit: "To
determine the time in seconds, the value returned by clock() should be
divided by the value of the macro CLOCKS_PER_SEC".

Maybe you'll get the desired result with usleep() function, or get the
time from gettimeofday().
