Time is like you say, a perception. And perceptions is a state of mind.

So you question translated for what you ask for is: Manipulating your mind?
Manipulation in itself is the urge to transform someone or something that would naturally resist the manipulative outcome. So the word manipulation essentially refers to cheating the natural change-process in some form. But I assume that your intention wasn't really to learn or use manipulation as something negative.

May I ask why you find interest in manipulating the perception of time?
