Well, even if your program doesn't sleep, doesn't get stuck waiting for
vertical retrace, I/O, etc - clock() still won't return 'realtime' if
there is another program running somewhere in the machine.  This is
*UNIX* and you should certainly expect there to be other programs
sharing your resources.
