Abstract: PROBLEM TO BE SOLVED: To precisely adjust control functions by equipping respective nodes with clocks which hold the real world time, synchronizing the clocks with the real world time according to a synchronization protocol, and synchronizing control functions of the decentralization type system according to the real word time of the clocks. SOLUTION: This decentralized type system 10 is equipped with one group of nodes 20 to 24, which communicate with one another via a communication link 12 and equipped with the real world clocks 30 to 34. The real world clocks 30 to 34 are real-time clocks which reflect a real world time base such as the agreement, which is already known as 'Greenwich Mean Time.' The nodes 20 to 24 synchronize the time values that the real world clocks 30 to 40 hold according to the synchronization protocol. The control functions of the decentralization type system 10 are synchronized, on the basis of the real world time base provided by the real world clocks 30 to 34 for the synchronization.

Abstract: PROBLEM TO BE SOLVED: To distribute a standard time value to decentralized nodes through a communication link. SOLUTION: Each node which is decentralized through are communication link 12 in this system 10 includes a slave clock which synchronizes a slave time value by using a synchronizing protocol. This system 10 includes a trackable time generating mechanism which generates a trackable time value and a master node having a master clock which synchronizes a master time value with the trackable time and distributes a master time value to slave blocks through the communication link 12. Consequently, the local time of each decentralized node always accurately matches the single standard time.
