I'm afraid that physical time travel is out of the question. Newton's First law of physics states that matter can not be created or destroyed, just transformed. So every molecule that makes up your body has other commitments in the future and / or the past.
If I ask you what you are doing right now, there is no real answer without refering to the past or the future, living in the present is impossible. You plan for the future and it is the past.:
