Just a quick question
is there a difference between
t1 = cputitme();
t2 = cputime();
t = t2 - t1
and
t1 = cputtime();
t = cputime() - t1;
Both give different answers to me. In fact the second one is way faster for my program.

There is no significant difference, except that you have spelled it three different ways, so it is unlikely the code you wrote actually works. ;)
But what do you mean by one of those calls is faster than the other? cputime does not measure time well enough to clearly be able to tell you such a short time interval. Even the slightest variation of something running on your computer in the background will be enough to blow that tiny difference out of the water.
