Our main goal in this paper is to analyse if it is possible to build some suitable Temporal-Epistemic Systems. However, the main difficulties in order to aim this goal come from the fact of having to combine an absolute temporal perspective with a relative (to each agent) epistemic perspective; that is, on one hand, temporal points (instants) are determined from the point of view of an observer placed outside the world, and, on the other hand, the epistemic alternatives of each agent (in each instant) are relative to that agent. We think that some of these difficulties could be solved with the help of hybrid logics, because this kind of logics simplifies the combination of temporal and epistemic systems, and so we can avoid building highly complicated models.
