In a cyber-physical system (CPS), the events start or finish in a sequence of time. The sequence can be called chronological order. Chronological order relationship is essential in determining system status and providing decision reference in feedback control related to IoT areas. However, the correctness of the order obtained is vulnerable to many factors. This paper delves into typical events in a closed cyber-physical environment and the chronological relationship between them, gives a criteria to tell if their respective sensors can distinguish the chronological order of two events. Besides, a framework to reconstruct the chronological order of inter-dependent, simple events is proposed. Finally, an experiment based on the framework is conducted with the ability to identify the underlying chronological order in a system.
