[mathm mason]"i want to add time in and time out for an effect on AFTER EFFECTS CS5"
I'm not entirely sure I understand what you're asking for, but it sounds like you're interested in changing an effect over time. This is one of the basic fundamentals of After Effects, so if you're new to the application, check out Todd Kopriva's blog entry Getting started with After Effects.
Apologies if I've misunderstood!
