We "see" time everywhere because it's the way we see. You can't "unsee" light that's caused neurons to fire in your nut, or what? The idea of CPT invariance is an idea, reality tells us Time goes forward; not backward, [not] for anything.
There is only change, direction has no meaning in this context.
If I have a pipette I can suck up a liquid, squirt it out, and suck it up again. The sequence is repeatable and
reversible, has time gone in reverse because I can
reverse an action? Of course not.
