PROBLEM TO BE SOLVED: To provide a device for measuring organism information and program, capable of correcting an internal clock even when time correction is not performed due to some cause.SOLUTION: A first correction part 18 performs the time correction of an internal clock 14 using time information and stores the amount of time correction showing the size of time lag in a storage part 15 when the time correction is performed. A second correction part 19 performs the time correction of the internal clock 14 using the history of the amount of time correction stored in the storage part 15 when detecting that the first correction part 18 does not normally perform the time correction at a specified timing.SELECTED DRAWING: Figure 1
