Which is not a time system?

Which is not a time system? Correct Answer Polar time

Out of the options, Polar time is incorrect. Others are different types of time systems. The Julian day is the number of days since noon UT on January 1, 4713 BC. Atomic time defines one second as the time it takes a Cesium-133 atom at the ground state to oscillate exactly 9,192,631,770 times. Universal time is determined by the sun’s passage across the Greenwich meridian, which is 0° terrestrial longitude.
