Even the Earth's rotation rate has more drift and variation in drift than an atomic clock due to tidal acceleration and other effects. The principle behind the atomic clock has enabled scientists to re-define the SI unit second in terms of exactly 9 192 631 770 oscillations of the caesium-133 atom. The precision of these oscillations allows ...
Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift , caused by clocks counting time at slightly different rates.
When a pulse of N consecutive zero bits are sent, clock drift may cause the hardware to apparently detect N-1 zero bits or N+1 zero bits – both kinds of errors are called bit slip. [ 1 ] [ 2 ] Thus one prevents long strings without change via such devices as run length limited codes.

Most reliable sources (e.g. ) seem to use "skew" to mean rate of change of offset (i.e. how fast/slow it runs" and "drift" to mean rate of change of skew (i.e. how stable a clock is). It's a pity that this article uses both terms to mean a range of things, and irritating that "clock skew" is used by the semiconductor industry to mean something ...
The clock tower is situated in Tirana's city center, adjacent to Et'hem Bey Mosque. It is a type III clock tower, characterized by three floors and represents the first variant of this type, where the second floor is open. [a] The tower stands on a 1-meter-high plinth with a square base measuring 4.27 x 4.28 meters. The stones for its ...
A clock mechanism may be used to control a device according to time, e.g. a central heating system, a VCR, or a time bomb (see: digital counter). Such mechanisms are usually called timers . Clock mechanisms are also used to drive devices such as solar trackers and astronomical telescopes , which have to turn at accurately controlled speeds to ...
DUT1 is a time correction equal to the difference between Universal Time , which is defined by Earth's rotation, and Coordinated Universal Time (UTC), which is defined by a network of precision atomic clocks, with a precision of +/- 0.1s [1] [2]. DUT1 = UT1 − UTC (with a precision of +/- 0.1s)
