A time standard is a specification for measuring time: either the rate at which time passes; or points in time; or both. In modern times, several time specifications have been officially recognized as standards, where formerly they were matters of custom and practice. An example of a kind of time standard can be a time scale, specifying a method for measuring divisions of time. A standard for civil time can specify both time intervals and time-of-day.
Standardized time measurements are made using a clock to count periods of some cyclic change, which may be either the changes of a natural phenomenon or of an artificial machine.
Historically, time standards were often based on the Earth's rotational period. From the late 17th century to the 19th century it was assumed that the Earth's daily rotational rate was constant. Astronomical observations of several kinds, including eclipse records, studied in the 19th century, raised suspicions that the rate at which Earth rotates is gradually slowing and also shows small-scale irregularities, and this was confirmed in the early twentieth century. Time standards based on Earth rotation were replaced (or initially supplemented) for astronomical use from 1952 onwards by an ephemeris time standard based on the Earth's orbital period and in practice on the motion of the Moon. The invention in 1955 of the caesium atomic clock has led to the replacement of older and purely astronomical time standards, for most practical purposes, by newer time standards based wholly or partly on atomic time.
NIST has officially launched NIST-F2 More Info: http://go.usa.gov/kqbQ. NIST-F2, a new atomic clock based on a "fountain" of cesium atoms, is now the U.S. civilian time standard. NIST-F2 will neither gain nor lose one second in 300 million years, making it more than twice as accurate as its predecessor, NIST-F1, which was the U.S. civilian time and frequency standard since 1999.
Poison's nothing but a good time adjusted to standard tuning.

Drummer Joe Morello's second date as a leader for DMP (and only third since 1962) uses the same lineup of musicians as the previous one: tenor saxophonist Ralph Lalama, pianist Greg Kogan and bassist Gary Mazzaroppi. Although a powerful drummer, Morello is mostly content to feature his sidemen, particularly the up-and-coming Lalama, whose style fits perfectly into late-1950s hard bop. Highlights of the often delightful bop set include "Paper Moon," "Bye Bye Blackbird," "Doxy" and "Take Five."(AllMusic)... _______________________________________________________________________________________________ Tracklist: 01.Paper Moon (Rose/Harburg/Arlen)...(00:00) 02.When You Wish Upon A Star (Harline/Washington/Porter)...(05:35) 03.One For Amos (Jones)...(12:17) 04.Take Five (Desmond)...(17:29...
