Abstract: A controller includes circuitry configured to: receive global time data indicating a global time associated with an external global clock; synchronize an internal controller clock of the controller with the global clock based on the global time; set a controller time based on the synchronized controller clock; and transmit controller time data indicating the controller time to at least one local device through periodic communication.
