Question

1 11.4.2 What does the abbreviation UTC stand for? How is it related to the time zones around the world? Read the text to find out.​

Answer 1

Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time.

Answer 2

The abbreviation UTC stands for Coordinated Universal Time. It is a standard timekeeping system used as a reference for time synchronization globally. UTC is based on International Atomic Time (TAI) with leap seconds added at irregular intervals to compensate for the Earth's slowing rotation.

UTC serves as a common time reference for various purposes, including international communications, aviation, weather forecasting, and global computer networks. It allows different locations around the world to have a standardized time scale, facilitating coordination and avoiding confusion.

Time zones are regions with the same standard time offset from UTC. They are typically defined by the number of hours ahead or behind UTC they are. For example, UTC+2 denotes a time zone two hours ahead of UTC, while UTC-5 represents a time zone five hours behind UTC.

Time zones are essential for maintaining consistent time across different regions, as they account for the Earth's rotation and the need for daylight saving adjustments in some areas. By referencing UTC, time zones can be easily determined and converted, allowing people to coordinate activities and schedules across different locations accurately.
