ABSTRACT:
In a system in which a first computer transmits data to a second computer, the first computer transmits data conveying time information to the second computer, with the information expressing a first time point that occurs prior to commencement of the transmission and, following reception of the time information, the second computer compares the first time point information with a current time point, to thereby obtain a communication delay amount that includes a delay in transmitting data from the first to the second computer.
