Actually isn't time's arrow pointing in the direction of information being increased? Entropy as defined in Claude Shannon's information-theoretic sense is actually correlated with information. More entropy means more information. And indeed, intuitively, we have more information as time goes on (about the past) and not the other way around. If you assume that information does not travel backwards in time - then you once again get that information increases in the direction of time. The article stated it wrong.
