This paper continues a series of articles presenting authors’ ideas and results relating to development of category-theoretic methods for specifying and analysing models of logical time in distributed systems including cyber-physical systems. Results of this paper generalise results of the previous articles by the way of generalising the concepts of a clock structure and a schedule. The paper shows that all the main results obtained earlier remain valid for the generalisation under consideration. In addition, the proposed generalisation gives a tool for identifying in category-theoretic terms the concepts of global clocks and synchronisation processes.
