My gut would be to loose the prologue you have, as far as I can tell it only gives us one criticial piece of information - man out of time - which I guess given the title is the whole point of the book. It's hard to say without seeing chapter 1, but they say "if in doubt, leave it out."
<Added>Sorry - that was a bit of chapter 1 I read - so forget the above, as I havne't read the prologue. But my "in doubt" stands!
