Usually the story is that Supergirl was chasing a missile heading to Earth so as she flew, she was going so fast that she travelled through time. (This was back when the Kryptonains were able to be as fast as Speedsters and that is what started the Superman vs. Flash race debate) However now it would have to be different and she would have to return sooner.
