NBC has announced a new time-travel series called "Journeyman". The
premiere will air on Monday, 24 September 2007 @ 9:00 pm (CDT).

Information on this series is still a bit sparse, but evidently the
premise is as follows. Dan (Kevin Mckidd) is a guy that inexplicably
ends up being able to time-travel. So he goes around trying to use it
for good and ends up screwing things up (?).

Anyway, here are some links:

Well, we'll see what happens. Hope they do better than "Quantum Leap".
