spoiler alert.
Anytime you get lost in the space-time continuum the solution is simple one. Send your daughter back in time data on how to travel in five dimensions and blackholes via your old bookshelf into the vintage analog watches. Yup. Easy one. Could have crack this one, too. Why using satelittes when sending data via bookshelf to watches is much better.
P.S. I loved the movie, but putting it like this it is just ridiculous :oD
