Time-zone
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. All time zones are defined as offsets from Coordinated Universal Time (UTC), ranging from UTC−12:00 to UTC+14:00. The offsets are usually a whole number of hours, but a few zones are offset by an additional 30 or 45 minutes, such as in India, South Australia and Nepal. Some areas of higher latitude use daylight saving time for about half of the year, typically by adding one hour to local time during spring and summer. List of UTC offsets In the table below, the locations that use daylight saving time (DST) are listed in their UTC offset when DST is ''not'' in effect. When DST is in effect, approximately during spring and summer, their UTC offset is inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time In Australia
Australia uses three main time zones: Australian Western Standard Time (AWST; UTC+08:00), Australian Central Standard Time (ACST; UTC+09:30), and Australian Eastern Standard Time (AEST; UTC+10:00). Time is regulated by the individual state governments, some of which observe daylight saving time (DST). Australia's external territories observe different time zones. Standard time was introduced in the 1890s when all of the Australian colonies adopted it. Before the switch to standard time zones, each local city or town was free to determine its local time, called local mean time. Now, Western Australia uses Western Standard Time; South Australia and the Northern Territory use Central Standard Time; while New South Wales, Queensland, Tasmania, Victoria, Jervis Bay Territory, and the Australian Capital Territory use Eastern Standard Time. Daylight saving time (+1 hour) is used in jurisdictions in the south and south-east: South Australia, New South Wales, Victoria, Tasmania, ...

Indian Standard Time
Indian Standard Time (IST), sometimes also called India Standard Time, is the time zone observed throughout India, with a time offset of UTC+05:30. India does not observe daylight saving time or other seasonal adjustments. In military and aviation time, IST is designated E* ("Echo-Star"). It is indicated as Asia/Kolkata in the IANA time zone database. History After Independence in 1947, the Union government established IST as the official time for the whole country, although Kolkata and Mumbai retained their own local time (known as Calcutta Time and Bombay Time) until 1948 and 1955, respectively. The Central observatory was moved from Chennai to a location at Shankargarh Fort in Allahabad district, so that it would be as close to UTC+05:30 as possible. Daylight Saving Time (DST) was used briefly during the China–India War of 1962 and the Indo-Pakistani Wars of 1965 and 1971. Calculation Indian Standard Time is calculated from the clock tower in Mirzapur nea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daylight Saving Time
Daylight saving time (DST), also referred to as daylight savings time or simply daylight time (United States, Canada, and Australia), and summer time (United Kingdom, European Union, and others), is the practice of advancing clocks (typically by one hour) during warmer months so that darkness falls at a later clock time. The typical implementation of DST is to set clocks forward by one hour in the spring (" spring forward"), and to set clocks back by one hour in the fall ("fall back") to return to standard time. As a result, there is one 23-hour day in early spring and one 25-hour day in the middle of autumn. The idea of aligning waking hours to daylight hours to conserve candles was first proposed in 1784 by U.S. polymath Benjamin Franklin. In a satirical letter to the editor of ''The Journal of Paris'', Franklin suggested that waking up earlier in the summer would economize on candle usage; and calculated considerable savings. In 1895, New Zealand entomologist and astrono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time In Alaska
Alaska is officially covered by two time zones - the Alaska Time Zone and the Hawaii-Aleutian Time Zone. The Hawaii-Aleutian Time Zone is used for the Aleutian Islands west of 169°30′W (Islands of Four Mountains, Andreanof Islands, Rat Islands and Near Islands), and the rest of the state uses the Alaska Time Zone. The entirety of Alaska observes daylight saving time. The town of Hyder, because it essentially is a single town split by the border between the United States and Canada, unofficially observes Pacific Time including DST ( UTC−08:00, DST UTC−07:00) like its neighbor Stewart, British Columbia, with the exception of the U.S. Post Office (because it is a federal facility). History As part of Russian America, Alaska used the Julian calendar and the same day of the week as Asia. In 1867, Alaska became a United States territory (Alaska Purchase) and began using the Gregorian calendar and the same day of the week as the Americas. The switch was achieved by repeating the ...

Time In Hawaii
Hawaii is located in the Hawaii–Aleutian Time Zone (HST; UTC−10:00) and does not observe daylight saving time. Hawaii adopted HST in 1947, switching from UTC−10:30, which it had used since 1896.Schmitt, Robert G. and Cox, Doak G. (1997Hawaiian Time( eVols). Hawaiian Journal of History, vol. 26. Hawaiian Historical Society. p. 13. Retrieved 10 May 2021. Effects of standard time on television broadcasting Most cable providers in Hawaii carry the west coast feed of television networks. Hawaii is located two hours behind the Pacific Time Zone, so programs will air in Hawaii two hours later than their advertised start time. Between March and November, when daylight saving time is in effect in most of the contiguous United States, this is increased to three hours as Hawaii does not observe daylight saving time.

Nepal Time
Nepal Standard Time (NPT) is the time zone for Nepal. With a time offset from Coordinated Universal Time (UTC) of UTC+05:45 all over Nepal, it is one of only three time zones with a 45-minute offset from UTC.The others are Chatham Island Standard Time, with an offset of UTC+12:45, and the unofficial Australian Central Western Time, with an offset of UTC+08:45. NPT is an approximation of Kathmandu mean time, which is 5:41:16 ahead of UTC. The standard meridian passes through the peak of Gaurishankar mountain about east of Kathmandu. Nepal used local solar time until 1920, in Kathmandu UTC+05:41:16.

World Time Zones Map
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In '' scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
