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.
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 ...
This is an accepted version of this page This is the latest accepted revision, reviewed on 5 December 2024. Primary time standard "UTC" redirects here. For the time zone between UTC−1 and UTC+1, see UTC+00:00. For other uses, see UTC (disambiguation). It has been suggested that UTC offset be merged into this article. (Discuss) Proposed since December 2024. Current time zones Coordinated ...
English: Plot showing the difference UT1−UTC in seconds. Vertical segments correspond to leap seconds . Red part of graph was prediction (future values) at the time the file was made.
Screenshot of the UTC clock from time.gov during the leap second on 31 December 2016.. A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC), to accommodate the difference between precise time (International Atomic Time (TAI), as measured by atomic clocks) and imprecise observed solar time (), which varies due to irregularities and long-term ...

Graph showing the difference between UTC (based on an atomic clock with leap seconds) and UT1 (based on the movement of the Earth). This graph illustrates the effect of leap seconds, along with why there have been so few leap seconds in the past several years. Used in Leap second, Coordinated Universal Time and DUT1. Nominate and support.
UTC +01:00 is an identifier for a time offset from UTC of +01:00. In ISO 8601, the associated time would be written as 2019-02-07T23:28:34+01:00. This time is used in: Central European Time; West Africa Time; Western European Summer Time. British Summer Time; Irish Standard Time
