Abstract: A biological information processing system includes a biological information measurement device configured to measure biological information of a subject; and a control device configured to manage the biological information. The control device includes, among other things, an analysis section configured to analyze flag information contained in measurement data received from the biological information measurement device, and a data correction section configured to, when an analysis conducted by an analysis section shows that a measurement date and time are a provisional date and time, correct the measurement date and time information on the basis of a time discrepancy between measurement-side clock information and control-side clock information.
