INFORMATION PROCESSING APPARATUS, TIME SYNCHRONIZATION METHOD, AND COMPUTER-READABLE RECORDING MEDIUM RECORDING TIME SYNCHRONIZATION PROGRAM

摘要

An information processing apparatus includes: a memory configured to store first system time; and a processor configured to: receive, from an information acquisition apparatus after the first system time is written in the memory, first information acquired by the information acquisition apparatus and first time information indicating acquisition time of the first information; receive, from the information acquisition apparatus after receiving the first information and the first time information, second information and second time information indicating acquisition time of the second information; converting, based on the first system time, reception time at which the first information and the first time information are received into second system time; convert, based on the second system time and the first time information, the second time information into third system time; attach the second system time to the first information; and attach the third system time to the second information.
