What is a System of measuring the passing hours?

Answer 1

A system of measuring the passing hours typically refers to timekeeping methods that track the progression of time, such as clocks and watches. These systems can be based on various units, including seconds, minutes, and hours, and often rely on consistent periodic events, like the Earth's rotation or oscillations of a pendulum. Different cultures have developed unique timekeeping systems, but the modern standard is the 24-hour clock, which divides the day into two 12-hour segments.
