McTaggart famously argued that time is unreal. Today, almost no one agrees with his conclusion.1 But his argument remains the locus classicus for both the A–theory and the B-theory of time. I want to show how McTaggart's argument provided the impetus for both of these opposing views of the nature of time. I will also present and defend what I take to be the correct view of the nature of time.
