In this chapter, we study a process for changing a given quasi-flow by altering the time taken to go from one point in the underlying space to another. The orbits of the new quasi-flow sometimes coincide with those of the old quasi-flow. However, in general, if two points lie in an orbit of the old quasi-flow, the new time between them might be infinite, in which case they would lie in different orbits of the new quasi-flow.
