RESOURCE INFORMATION MANAGING DEVICE, SYSTEM, METHOD, AND PROGRAM

摘要

It is possible to time-sequentially manage resource information even in a large-scale distribution system not synchronized or in an information terminal network. A resource information collection device (5) checks time synchronization with a resource information generation device (6) when collecting resource information from the resource information generation device (6). If not synchronized, a generation time corrected according to the time of the resource information collection device (5) is recorded on the resource information. A resource information reference device (4) checks time synchronization with the resource information collection device (5) when referencing the resource information in the resource information collection device (5). If not synchronized, a generation time corrected according to the time of the resource information reference device (4) is recorded on the resource information.
