In this article we reconstruct the Frauchiger and Renner´s argument taking into account that the assertions of the argument are made at dierent times. In order to do this, we use a formalism of quantum histories: the Theory of Consistent Histories. We show that the supposedly contradictory conclusion of the argument requires computing probabilities in a family of histories that does not satisfy the consistency condition, i.e. an invalid family of histories for the theory.
