 Here is one reason why we might think that Presentism does not, in the end, help with the problem of temporary intrinsics. Suppose that, at t1, we send a circular object forward in time to t2. At t2 the shape of the circular object changes so that it becomes elliptical. Retaining its elliptical shape the object is sent back to t1. Even if Presentism is true at t1 we have an object with incompatible intrinsic properties.
