In a few regions, however, the legal time kept is not that of one of the 24 standard time zones because half-hour or quarter-hour differences are in effect there. Other organizations may use this image without charge for editorial articles that mention NIST in accompanying text or a caption. contact NIST at about use of this image. Time is the same throughout each zone and differs from the international basis of legal and scientific time, Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC), by an integral number of hours minutes and seconds are the same. Use the time zone map to find out what time it is in different locations across the world at any given moment. This is a map created by NIST showing time zones around the world. These meridians are theoretically the centres of 24 standard time zones in practice, the zones have in many cases been subdivided or altered in shape for the convenience of inhabitants. World Time Buddy (WTB) is a convenient world clock, a time zone converter, and an online meeting scheduler. The present system employs 24 standard meridians of longitude (lines running from the North Pole to the South, at right angles to the Equator) 15º apart, starting with the prime meridian through Greenwich, England. Takes into account all DST clock changes. World time and date for cities in all time zones. UTC is Coordinated Universal Time, GMT is Greenwich Mean Time. With incomparable time-telling precision, World Clock is the perfect point of reference for travelers and business people alike. UTC (GMT/Zulu)-time: Saturday, Maat 16:09:25. Following this initiative, in 1884 delegates from 27 nations met in Washington, D.C., for the MeridianĬonference and agreed on a system basically the same as that now in use. provides accurate world time, statistics and weather in major cities across the world. Sir Sandford Fleming, a Canadian railway planner and engineer, outlined a plan for worldwide standard time in the late 1870s. It may also be of great use for those who are often traveling. The need for a standard time was felt most particularly in the United States and Canada, where several extensive railway routes passed through places that differed by several hours in local time. We have 24 different time zones in the world. Some such standard became increasingly necessary with the development of rapid railway systems and the consequent confusion of schedules that used scores of different local times kept in separate communities (local time varies continuously with change in longitude). The concept of standard time was adopted in the late 19th century in an attempt to end the confusion that was caused by each community's use of its own solar time.
The whole of China, one of the largest countries in the world, has decided to adopt a single time zone. Standard time the time of a town, region or country that is established by law or
