Local Mean Time

Local mean time is a form of solar time that corrects the variations of local apparent time, forming a uniform time scale at a specific longitude. Its uniformity depends only on the accuracy of the clocks used to measure it.

Local mean time was used from the early 19th century, when local solar time or sundial time was last used, until standard time was adopted on various dates in the several countries. Standard time means that the same time is used throughout some region—usually, it was either offset from Greenwich Mean Time or was the local mean time of the capital of the region. The difference between local mean time and local apparent time is the equation of time.

Famous quotes containing the words local and/or time:

    His farm was “grounds,” and not a farm at all;
    His house among the local sheds and shanties
    Rose like a factor’s at a trading station.
    Robert Frost (1874–1963)

    I have a sense of going my own way, and I don’t really think much about whether it’s going against the grain. I don’t really want to spend a lot of time worrying about how I am perceived by other people.
    Kathleen Collins (1931–1988)
