  • Management device, system, and method
    Patent number: 10097298
    Abstract: According to an embodiment, a management device includes a calculator and a notifier. The calculator calculates a time offset for each of a plurality of master devices each performing, when a measured time reaches a certain time, time synchronization with a slave device, which is a management target, at the measured time. The notifier notifies each master device of a change notification causing the master device to change the measured time in the master device to a time obtained by offsetting the measured time with the time offset.

  • TIME SYNCHRONIZATION CLIENT, SYNCHRONIZATION METHOD, COMPUTER PROGRAM PRODUCT, AND SYNCHRONIZATION SYSTEM
    Publication number: 20180191485
    Abstract: According to an embodiment, a time synchronization client includes one or more processors. The one or more processors are configured to perform time synchronization according to time information received by communicating with a time synchronization server at every synchronization period, and determine a second synchronization period shorter than a first synchronization period of when synchronization accuracy is a target level or more, as the synchronization period, when an elapsed time from activation of the time synchronization client does not exceed a judgment time.

  • Information processing apparatus and communication device
    Patent number: 9985754
    Abstract: An information processing apparatus comprises a first circuitry and a second circuitry. The first circuitry first/second demand response requests from first/second communication devices. The second circuitry creates first request content information representing contents of the first demand response request, sends it to a time-stamping authority, and acquires first time certification information containing a time stamp that the time-stamping authority issues for the first demand response request. The second circuitry stores the first time certification information in a storage device to be associates with the first demand response request; and determine, when the second demand response request is received, whether the second demand response request is retransmission of the first demand response request.
