Well, STAR TREK did.  There were at least two episodes wherein the Warp
Drives (plus extraneous things like black holes) where used for time
travel.

See Larry Niven's _All_The_Myriad_Ways_ for why he (and I) hate the
standard parallel universe concept (cross-time).  If it really bugs you,
just go thru all ftl books and replace "spaceship" with "parallel
universe machine."
