Apparently the answer lies in the system of time measurement used by humans and the way the earth rotates around its axis.

First, let’s discuss the system of measuring time. Humans use a time system known as standard time or universal coordination time known as Coordinated Universal Time (UTC).

UTC uses atomic time as a reference and is adopted worldwide. However, for practical daily needs, each country or region usually uses a time zone that is determined based on its geographical location.

For example, some countries use the Greenwich Standard Time Zone (GMT), while others use a time zone set based on the time difference with GMT.

The time difference is also affected by the Earth’s rotation. Earth rotates around its axis in 24 hours, which results in day and night cycles.

However, this motion is not uniform, and there are small variations in the Earth’s rotational speed over time.
