Key 'graph excerpt (emphasis mine):
How does this resolve the arrow of time problem? Well, put simply, running time in one direction allows records to be kept and events to be observed. In the other direction, observation becomes impossible. Therefore, although time could be running in either direction (or, who knows, both directions simultaneously), it is only possible for any observer (not necessarily a human one) to experience time in the forward direction.
We now return to our regularly scheduled programming. That is all.
