I never thought about the 100% solution bit, though I guess it does explain alot.
As for Tempus Anyone, the time lapse reminded me of the Chronicles of Narnia by C.S. Lewis. No matter how much time passed in Narnia, even if it was years, the children always returned barely a second after they left. And when a year passed in our time, thousands of years had passed on Narnia. (See
The Lion, the Witch, and the Wardrobe and
Prince Caspian )
