Current belief change literature is largely confined to atemporal belief change - the temporal element of beliefs is not explicitly recognized or represented. In this paper, we present a temporal belief change framework that is based on applying Spohn's theory of ranking functions to certain temporal semantic objects that we call 'histories'. The resulting framework allows us to address a class of problems for which Jeffery's general conditionalization, and Spohn's cardinality of the ranks, as well as the dependencies between beliefs play a central role. This allows us to lend further support to the argument that the application of the AGM theory is not necessarily limited to a static world. We also present an interpretation of belief update in the context of ranking-functions that has been missing in the literature.
