This work reviews the understanding of the direction of time introduced by Hans Reichenbach, including the fundamental relation of the perceived flow of time to the second law of thermodynamics (i.e. the Boltzmann time hypothesis), and the principle of parallelism of entropy increase. An example of a mixing process with quantum effects, which is advanced here in conjunction with Reichenbach’s ideas, indicates the existence of a physical mechanism that reflects global conditions prevailing in the universe and enacts the direction of time locally (i.e. the “time primer”). Generally, this mechanism, whose effects are often enacted by presuming antecedent causality, remains unknown at present. The possibility of experimental detection of the time primer is also discussed: if the time primer is CPT-invariant,its detection may be possible in high-energy experiments under the current level of technology.
