Coordinated Universal Time ( UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce.

O Tempo Universal Coordenado (abreviado internacionalmente como UTC, um meio-termo entre o inglês Coordinated Universal Time e o francês Temps Universel Coordonné[ 1][ 2][ 3] ), também conhecido como tempo civil, é o fuso horário de referência a partir do qual se calculam todas as outras zonas horárias do mundo.
Universal Time (UT or UT1) is a time standard based on Earth's rotation. While originally it was mean solar time at 0° longitude, precise measurements of the Sun are difficult. Therefore, UT1 is computed from a measure of the Earth's angle with respect to the International Celestial Reference Frame (ICRF), called the Earth Rotation ...
Each time zone is defined by a standard offset from Coordinated Universal Time (UTC). The offsets range from UTC−12:00 to UTC+14:00, and are usually a whole number of hours, but a few zones are offset by an additional 30 or 45 minutes, such as in India and Nepal.
Coordinated Universal Time (or UTC) is the standard time system of the world. It is the standard by which the world regulates clocks and time. It is, within about 1 second, mean solar time at 0° longitude. The standard before was Greenwich Mean Time (GMT). UTC and GMT are almost the same.
This is a list of the UTC time offsets, showing the difference in hours and minutes from Coordinated Universal Time (UTC), from the westernmost (−12:00) to the easternmost (+14:00). It includes countries and regions that observe them during standard time or year-round.
Learn about UTC, the 24-hour time scale that synchronizes the world's clocks. Find out how UTC is based on atomic clocks and Earth's rotation, and how it differs from GMT and other time zones.
