The Accidental Time Machine by Joe Haldeman
Matt Fuller is your average guy, a bit on the lazy side, stuck in a dead end job as a lab assistant at MIT. He is building a calibrator when it suddenly disappears and then reappears a second later. He experiments with the machine and realizes that he has built a time machine. This particular time machine only goes forward in time and the interval it travels into the future increases by 12 each time.
If Matt is touching the time machine, he also travels with it. With nothing going in his life, he decides to travel. The first few times, he only travels a little bit, but he keeps ending up situations where his only escape is to jump forward again. Haldeman offers a unique perspective on the world in each of the futures presented. When he meets and falls for a young woman, he must decide what is best for the two of them and what kind of future world he wants to live in.
This book is a fun and fast sci fi read. It will appeal to sci fi fans as well as your average fiction reader. Nothing is too far "out there" or fantastical for the average readers' taste.
