Time is a sign of the instantaneous time scale.

Note. The actual application of the term to the year, month, week and day to represent.

Between two defined moments elapsed time.

Having the repetitive nature of the period.

The number of cycles per second.

Note. This value is expressed in hertz (Hz), for example. 32.768kHz = 32768Hz, 8MHz = 8000000Hz. For balance and balance spring oscillating system, Given half cycle per hour, for example. 2.5Hz = 18000 times/h.
