Standard Time
Standard time is the synchronisation of clocks within a geographical region to a single time standard, rather than a local mean time standard. Generally, standard time agrees with the local mean time at some meridian that passes through the region, often near the centre of the region. Historically, standard time was established during the 19th century to aid weather forecasting and train travel. Applied globally in the 20th century, the geographical regions became time zones. The standard time in each time zone has come to be defined as an UTC offset, offset from Universal Time. A further offset is applied for part of the year in regions with daylight saving time. The adoption of standard time, because of the inseparable correspondence between time and longitude, solidified the concept of halving the globe into an eastern hemisphere, eastern and western hemisphere, with one prime meridian replacing the prime meridian#History, various prime meridians that had previously been us ...

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. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Atchison, Topeka and Santa Fe Railway , often referred to as the Santa Fe or AT&SF, was one of the larger railroads in the United States. The railroad was chartered in February 1859 to serve the cities of Atchison and Topeka, Kansas, and Santa Fe, New Mexico. The railroad reached the Kansas–Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farmland from the land grants that it was awarded by Congress. Despite being chartered to serve the city, the railroad chose to bypass Santa Fe, due to the engineering challenges of the mountainous terrain. Eventually a branch line from Lamy, New Mexico, brought the Santa Fe railroad to its namesake city. The Santa Fe was a pioneer in intermodal freight transport; at various times, it operated an airline, the short-lived Santa Fe Skyway, and the fleet of Santa Fe Railroad Tugboats. Its bus line extended passenger transportation to areas not acce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
