Events happen in time. And time is essentially tensed: there is past, present, future. D.H. Mellor, author of Real Time (and Real Time 2), suggests otherwise. In this podcast for Philosophy Bites he explains why time isn't tensed.
Free PDF files of two of Hugh Mellor's books are available here: The Matter of Chance and Matters of Metaphysics (a collection of 16 of his papers). Both are also available as books - see below.
