It has the same problem as Quantum Leap in that the time passing in one timeline takes exactly the same amount of time as time passing another timeline. It feels like a contrived scenario that only exists to create dramatic tension. Since the show got canceled, I don't know if it's ever explained, but the implication was that one "timeline" was essentially just a computer simulation in the other one... but if that's the case why not pause it? Why not adjust the parameters? Why can the simulation only be run in real-time? I don't really need an answer. I don't mind suspending my disbelief for a decent story, and this was a decent story. It just stood out for me because the time travel stuff stood in contrast to the more plausible "20 minutes into the future" setting that perhaps could've made a compelling story on its own.
