I do remember that show.  Interesting concept.  However it could cause a time paradox.

Dr. Olga Vukavitch



Or

Captain Frank Parker

With Captain Frank Parker traveling to his own time, he was in the same time stream as himself.  If he changes anything the future is altered.  It is the butterfly effect.
