摘要：My subject is time - a topic that many philosophers have found enigmatic. My aim is to suggest resolutions to some of the enigmas.! The particular enigmas I have in mind are time's flow, its direction, and its duration. There is, it seems to me, one key which unlocks all these problems. I will attempt to explain this in section 2. But first, I need some background explanation; for the key is made of a material that will be somewhat unfamiliar.
