I don't want to speculate exactly how influential my book was in the philosophy community. Barry liked it. He's one person. But whether or not that's true, I did certainly have in mind addressing questions that are of interest to both physicists and philosophers. In fact, the arrow of time was basically what got me into foundations of physics and natural philosophy. That's what I actually studied. The philosophy of science stuff was too much about theory change in methodology which was interesting, but not anything I wanted to do for a living.
