ABSTRACT:
A digital data recording apparatus, which can record the exact acquisition time of data, a sampling data identification method thereof, and a program for identifying sampling data, are provided. A CPU11reads out the program of a first conversion formula. The CPU11uses the first conversion formula to convert a time series of detection temperature data into a time series of actual oscillation frequencies f″ of a reference clock signal. At a subsequent step, the CPU11calculates the respective normal sampling timings employing the current time as a reference time by dividing a time series of count values by each of the actual oscillation frequencies f″ corresponding to the respective count values.
