We study continuous time random walk with the waiting time distribution having long-time tail t-α, 0 <α< 1. The fractal time behavior of the hopping event set is treated in a systematic and rigorous way. We construct a dynamic model which shows the fractal time behavior. The expertmenu of dispersion diffution in amorphous systems are well explained by our theory.
