Standardiaikaa

Standardiaikaa, also known as standard time, refers to the coordinated timekeeping system used in most countries around the world. It is based on the division of the day into 24 hours, each hour into 60 minutes, and each minute into 60 seconds. This system is governed by the International Telecommunication Union (ITU) and is maintained by timekeeping organizations and institutions.

Standard time is typically set to the local mean solar time of a specific longitude, known as the standard meridian. This ensures that within a given time zone, the sun reaches its highest point at approximately the same time each day. Time zones are typically one hour apart, with some exceptions for political or geographical reasons.

Standard time is used for various purposes, including scheduling, transportation, and communication. It helps to synchronize activities across different regions and facilitates the coordination of global events and operations. However, it also means that the local time of day can vary significantly from the standard time in different parts of the world.

In some regions, standard time is adjusted for daylight saving time (DST), which involves advancing the clock by one hour during the summer months. This is done to make better use of daylight and reduce energy consumption. However, the practice of DST is not universal and is not observed in all countries.

Standardiaikaa plays a crucial role in modern society, enabling the efficient functioning of global systems and the coordination of human activities across different time zones.
