:>Try this

:>  clock_t start, end;
:>  double timetaken;
:>
:>  start = clock();
:>  delay(2000);
:>  end = clock();
:>
:>  timetaken=(end-start)/CLK_TCK;
:>  printf("The time was: %f\n", timetaken);
:>  ...

:>It works for me. I guess somehow printf truncated the value.
:>Correct me if I am wrong.

Yes, I think you're wrong. The problem is that (end-start)/CLK_TCK is
an integer value, where printf is waiting for a float value. You
can try :
	printf("The time was: %f\n", 1.*(end - start) / CLK_TCK);
that should work.
