TIME SYNCHRONIZATION CONTROLLER, TIME SYNCHRONIZATION CONTROL SYSTEM, TIME SYNCHRONIZATION CONTROL METHOD, AND TIME SYNCHRONIZATION CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To perform time synchronization with high accuracy, when a specific device synchronizes the time information with other device, even if the time required for the processing performed by the specific device varies in accordance with the state of a system including the specific device.SOLUTION: A time synchronization controller 30 includes a storage section 31 for storing the current time information, outputted from a time output section 34, as second time information 310, upon receiving an input signal including first time information 400 received from an external device 40, and an update section 32 for updating the current time information outputted from the time output section 34, based on third time information 340, i.e., the current time information outputted from the time output section 34, when a signal processing section 33 performing predetermined signal processing for the input signal has finished the signal processing, the first time information 400, and the second time information 310 stored in the storage section 31.SELECTED DRAWING: Figure 4
