When considering how one ought to act in a given situation, one should be careful to avoid working under assumptions which preclude that situation.
So, when considering how one ought to act in the situation of having been moved to the past, one should not work under assumptions which preclude that situation.
For example, the presently-accepted theories of the nature of the universe, according to which the past is some real thing, preclude such a situation, so, having been moved to the past, one can deduce those theories to be wrong.
So, perhaps time is not some real thing, not something directly connected to the state of the world. Then where is it to which the person has been moved? Perhaps a previous state of the world has been re-established, either in the same world as the person was in, or in another. If it has been re-established in the same world as the person was in, then the person must realise that the nature of states of the world is one of fragility, and that the one the person did travel from is now deleted, and that if one wants to avoid the same thing happening again one must ensure that the mechanism by which one was transported into the present world-state must not be engaged again. If he does not ensure this, the universe may find itself locked in a loop, with the world only ever progressing to a certain point, before being deleted and the previous state being re-established.
