The Doomsday Clock is a metaphor for the likelihood of a human-made global catastrophe, set by the Bulletin of the Atomic Scientists based on various threats. The clock was first set to seven minutes to midnight in 1947 and has been adjusted 25 times since then, with the most recent setting at 90 seconds in 2023.
Coordinated Universal Time (UTC) is the primary time standard globally used to regulate clocks and time. It is based on atomic clocks and is not adjusted for daylight saving time. Learn about its history, uses, mechanism, and leap seconds.
Unix time 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.
Learn about the definition, operation and history of International Atomic Time (TAI), a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. TAI is a weighted average of over 450 atomic clocks worldwide and is the basis for Coordinated Universal Time (UTC), which has leap seconds.
Universal Time (UT or UT1) is a time standard based on Earth's rotation, computed from a measure of the Earth's angle with respect to the International Celestial Reference Frame. Learn about the origin, evolution and global usage of UT and its variations, such as Greenwich Mean Time, Coordinated Universal Time and DUT1.
A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. The web page shows a table of locations and their UTC offsets, ranging from UTC−12:00 to UTC+14:00, with or without daylight saving time.
Sidereal time is a system of timekeeping based on Earth's rotation relative to the fixed stars. Learn how it differs from solar time, how it is affected by precession, and how it is used in astronomy and geodesy.
Adjusted net income skyrocketed 131% to $562.5 million in the second quarter, topping a 20% net margin for the first time. It probably won't be the last time. Someone excited by what they're ...
