In data logging applications an apparatus for real-time stamping data includes a reference time base, a short stopwatch circuit operative for generating a short-time stamp, and a long stopwatch circuit operative for generating at intervals a long-time stamp. Data to be logged with the short-time stamp is combined therewith and stored. A controller circuit controls the storage of the data and of the long-time and the short-time stamps. The controller circuit stores the long-time stamp at predetermined intervals.
