Abstract
Provided are a communication device and a communication system capable of specifying a failure part in a network in which a time server and a communication path are made redundant.A communication device acquires time-related information from a plurality of time servers over a plurality of networks and compares the information to specify the failure part in the time servers or in the networks. A remote apparatus acquires time-related information from the communication device over the plurality of networks and compares the information to determine the failure of the communication device.
