International Atomic Time. 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 ...
A world clock is a clock which displays the time for various cities around the world. The display can take various forms: The clock face can incorporate multiple round analogue clocks with moving hands or multiple digital clocks with numeric readouts, with each clock being labelled with the name of a major city or time zone in the world. The ...
Geochron. Geochron, Inc. is an American company founded in 1965 by James Kilburg, [1] an inventor from Luxembourg. It is also the name of their flagship product, the Geochron Global Time Indicator. The Geochron was the first world clock to display day and night on a world map, showing the familiar "bell curve" of light and darkness.
Time zones of the world. A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.
Japan is an archipelagic country comprising a stratovolcanic archipelago over 3,000 km (1,900 mi) along the Pacific coast of East Asia. [8] It consists of 14,125 islands. [9] [10] The four main islands are Hokkaido, Honshu, Kyushu, and Shikoku. The other 14,120 islands are classified as "remote islands" by the Japanese government.
Hiroshima was the first military target of a nuclear weapon in history. This occurred on August 6, 1945, in the Pacific theatre of World War II, at 8:15 a.m., when the United States Army Air Forces (USAAF) dropped the atomic bomb " Little Boy " on the city. [5]
Daylight saving time by country. Daylight saving time (DST), also known as summer time, is the practice of advancing clocks during part of the year, typically by one hour around spring and summer, so that daylight ends at a later time of the day. As of 2024, DST is observed in most of Europe, most of North America and parts of Africa and Asia ...
Universal Time. 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 ...
