•  Atomic clock

  An atomic clock is a type of clock that uses an atomic resonance frequency standard as its timekeeping element. They are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the frequency of television broadcasts, and in global navigation satellite systems such as GPS.

•  Clock

  A clock is an instrument used to indicate, measure, keep, and co-ordinate time. The word clock is derived ultimately from the Celtic words clagan and clocca meaning "bell". For horologists and other specialists the term clock continues to mean exclusively a device with a striking mechanism for announcing intervals of time acoustically, by ringing a bell, a set of chimes, or a gong. A silent instrument lacking such a mechanism has traditionally been known as a timepiece.

•  Pendulum clock

  A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. From its invention in 1656 by Christiaan Huygens until the 1930s, the pendulum clock was the world's most accurate timekeeper, accounting for its widespread use. Pendulum clocks must be stationary to operate; any motion or accelerations will affect the motion of the pendulum, causing inaccuracies, so other mechanisms must be used in portable timepieces.

•  Isochronous

  Isochronous : From Greek iso, equal + chronos, time. It literally means to occur at the same time or at equal time intervals. In general English language, it refers to something that occurs at a regular interval, of the same duration; as opposed to synchronous which refers to more than one thing happening at the same time.

•  Reference clock

  A reference clock may refer to the following: A master clock used as a timekeeping standard to regulate or compare the accuracy of other clocks In computing, it is the clock signal frequency that is coordinated upon multiple times per cycle, as compared to the effective bandwidth produced by the multiplier effect

•  Slave clock

  In telecommunication, a slave clock is a clock that is coordinated with a master clock. Slave clock coordination is usually achieved by phase-locking the slave clock signal to a signal received from the master clock. To adjust for the transit time of the signal from the master clock to the slave clock, the phase of the slave clock may be adjusted with respect to the signal from the master clock so that both clocks are in phase.

•  Game clock

  A game clock consists of two adjacent clocks and buttons to stop one clock while starting the other, such that the two component clocks never run simultaneously. Game clocks are used in two-player games where the players move in turn. The purpose is to keep track of the total time each player takes for his or her own moves, and ensure that neither player overly delays the game. Game clocks were first used extensively in tournament chess, and are often referred to as chess clocks.

•  Sidereal time

  Astronomers use sidereal time as a way to keep track of the direction in which their telescopes need to be pointed to view any given star in the night sky. Just as the Sun and Moon appear to rise in the east and set in the west, so do the stars. A sidereal day is approximately 23 hours, 56 minutes, 4.091 seconds (23.93447 hours or 0.99726957 SI days), corresponding to the time it takes for the Earth to complete one rotation relative to the vernal equinox.

•  Longitude prize

  The Longitude Prize was a reward offered by the British government for a simple and practical method for the precise determination of a ship's longitude. The prize, established through an Act of Parliament in 1714, was administered by the Board of Longitude.

•  Watch

  A watch is a timepiece that is made to be worn on a person. It is usually a wristwatch, worn on the wrist with a strap or bracelet. In addition to the time, modern watches often display the day, date, month and year, and electronic watches may have many other functions. Most inexpensive and medium-priced watches used mainly for timekeeping are electronic watches with quartz movements.

•  Harrison, Michigan

  Harrison is a city in the U.S. state of Michigan. As of the 2000 census, the city population was 2,108. It is the county seat of Clare County. The city is named after U.S. President William Henry Harrison. Harrison is near the junction of US 127 and M-61. US 127 actually bypasses the city on the east, though a business route serves the downtown area. Clare is 14 miles south on US 127, while Grayling is 40 miles to the north. Harrison is bordered along its eastern side by Budd Lake.
