Which clock do scientist use to measure time?
Explanation: A newly-designed atomic clock uses entangled atoms to keep time even more precisely than its state-of-the-art counterparts. The design could help scientists detect dark matter and study gravity’s effect on time. Atomic clocks are the most precise timekeepers in the world.
How do scientists measure time?
Time can be measured using a simple pendulum, stopwatch, atomic clock. The time measuring instruments exhibit two basic components: (1) a regular, constant, or repetitive action to mark off equal increments of time, and (2) a means of keeping track of the increments of time and of displaying the result.
Do clocks really measure time?
If you stick to the Newtonian model of universe, then — yes, clocks do measure time. But to “measure” time, you must first define the least unit of change to act as a reference model. We call this a “second”.

Who invented time?
The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today’s clocks measure. For the Egyptians, and indeed for a further three millennia, the basic unit of time was the period of daylight.
