Meant to note: TimeWatch is now available for sale.

TimeWatch is Pelgrane Press’s time-travel RPG (uses GUMSHOE), and the books are very very pretty and very very nice. I got the books early via the Kickstarter, and I think that it may very well become the go-to game for time travel campaigns (not that there are all that many RPGs that concentrate on that, of course).  Plus, I have a campaign concept rattling around in my head that I know that the game will support. So, check it out.
