In this paper we discuss the traditional approaches to the problem of the arrow of time. On the basis of this discussion we adopt a global and nonentropic approach, according to which the arrow of time has a global origin and is an intrinsic, geometrical feature of space–time. Finally, we show how the global arrow is translated into local terms as a local time-asymmetric flux of energy.
