The atoms in this crystal arrange themselves in time as well as space experiencing cyclic time rather than the continuous time we experience. Already it has been established that the smaller anything becomes the more often time will flow backwards and modern science is poised to follow Alice down the rabbit hole in the near future. Assuming supersymmetry, it means an arbitrary number of ways can be used to manipulate time, but there would be four rudimentary ones such as accelerating towards the speed of light, the gravity of a black hole, etc.
Physicists have been saying for the last fifty years that a Theory of Everything is just around the corner and this kind of technology hints at Star Trek and Star Wars.
