2. List of measuring instruments - Wikipedia

   en.wikipedia.org/wiki/List_of_measuring_instruments

   In the past, a common time measuring instrument was the sundial. Today, the usual measuring instruments for time are clocks and watches. For highly accurate measurement of time an atomic clock is used. Stopwatches are also used to measure time in some sports.

3. History of timekeeping devices - Wikipedia

   en.wikipedia.org/wiki/History_of_timekeeping_devices

   The idea of using atomic transitions to measure time was first suggested by the British scientist Lord Kelvin in 1879, [204] although it was only in the 1930s with the development of magnetic resonance that there was a practical method for measuring time in this way. [205] A prototype ammonia maser device was built in 1948 at NIST. Although ...
