Document Type and Number:
Japanese Patent JP6487386
Kind Code:
B2
Abstract:
A server, method, program, recording medium, and system for maintaining accuracy of time of data without increasing frequency of synchronization processing. A synchronizing unit that executes synchronization processing at a server time T1 for synchronization between a time of a server and a time of an electronic device; a collecting unit that collects multiple n data segments and temporal data segments together from the electronic device from the time T1 to a server time T2 after the time T1, the server time T2 being a time when the synchronizing unit executes synchronization processing for synchronization between a time of the server and a time of the electronic device; and a correcting unit that corrects temporal data segments added to the n data segments based on a synchronization shift amount which is a time difference between the time T2 and temporal data T2′ added to data corresponding to the time T2.
