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. UTC has been widely embraced by most countries and ...
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. The main purpose of this page is to list the current standard time offsets ...
Unix time[ a] is a date and time representation widely used in computing. It measures time by the number of non- leap seconds that have elapsed since 00:00:00 UTC on 1st January 1970, the Unix epoch. In modern computing, values are sometimes stored with higher granularity, such as microseconds or nanoseconds .
Universal Time ( UT or UT1) is a time standard based on Earth's rotation. [ 1] 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 Angle ...
The large dial shows the ten hours of the decimal day in Arabic numerals, while the small dial shows the two 12-hour periods of the standard 24-hour day in Roman numerals. Decimal time is the representation of the time of day using units which are decimally related. This term is often used specifically to refer to the French Republican calendar ...
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.
UTC−08:00 (Zone 4 or Northwest Zone) – State of Baja California. UTC−07:00 (Zone 3 or Pacific Zone) – States of Baja California Sur, Chihuahua, Nayarit, Sinaloa and Sonora. UTC−06:00 (Zone 2 or Central Zone) – Most of Mexico. UTC−05:00 (Zone 1 or Southeast Zone) – State of Quintana Roo. Time in Mexico. Chile.
International Atomic Time (abbreviated TAI, from its French name temps atomique international[ 1]) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. [ 2] TAI is a weighted average of the time kept by over 450 atomic clocks in over 80 national laboratories worldwide. [ 3]
