Abstract: I begin by laying down three conditions which any theory of time should meet: it should accord with our view that certain statements about the past are true; that the truthmakers for those statements should be clear; and should accommodate the truth-value links between various times. I show how two different kinds of presentism cannot meet these requirements, including that put forward by Prior. I develop a version of presentism, analogous to ersatz modal realism in the possible worlds debate, which does satisfy the requirements.
