A memory device with circuitry for improving accuracy of a time estimate used to authenticate an entity and a method for use therewith are disclosed. In one embodiment, a memory device receives a request to authenticate an entity. Before attempting to authenticate the entity, the memory device determines if a new time stamp is needed. If a new time stamp is needed, the memory device receives the new time stamp and then attempts to authenticate the entity using a time estimate based on the new time stamp. In another embodiment, the memory device comprises a plurality of different time stamp update policies (TUPs) that specify when a new time stamp is needed, and the determination of whether a new time stamp is needed is based on a TUP associated with the entity. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.
