So my initial thought of Clark not making it back to the same present as Lois is correct. With that said, it's not clear whether Clark made it close to her timeline (i.e. around her birth or so) or whether he had to live out life from 1912 until the present. Poor Clark, if so.
Can't wait to see their reunion!!
CLARK: No. I'm just worried I'm a jinx.
JONATHAN: A jinx?
CLARK: Yeah. Let's face it, ever since she's known me, Lois's been kidnapped, frozen, pushed off buildings, almost stabbed, poisoned, buried alive and who knows what else, and it's all because of me.
-"Contact" (You're not her jinx, you're her blessing.)
