  2. Clock synchronization - Wikipedia

    en.wikipedia.org/wiki/Clock_synchronization

    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. There are several problems that occur as a result of ...

    In doing so, the timekeeper accidentally restarted the clock, leading to all of the remaining time being expelled. The only option to restore the time due to the state of fencing clocks at the time was to put a second on the clock, for which the real time left has been estimated to be far less than that. [3]

    The No-Slot Clock, also known as the Dallas Smartwatch (DS1216E), [1] was a 28-pin chip-like device that could be used directly in any Apple II or Apple II compatible with a 28-pin ROM. Dallas Semiconductor produced the device as an easy implementation for a real-time clock for a variety of applications.

    5.307 × 10 −10 – 8.349 × 10 −11 = 4.472 × 10 −10. This fraction is subtracted from 1 and multiplied by the pre-adjusted clock frequency of 10.23 MHz: (1 – 4.472 × 10 −10) × 10.23 = 10.22999999543. That is we need to slow the clocks down from 10.23 MHz to 10.22999999543 MHz in order to negate both time dilation effects.

    A real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in personal computers , servers and embedded systems , RTCs are present in almost any electronic device which needs to keep accurate time of day .

    On 18 September 2042, the Time of Day Clock (TODC) on the S/370 IBM mainframe and its successors, including the current zSeries, will roll over. [5] [61] Older TODCs were implemented as a 64-bit count of 2 −12 microsecond (0.244 ns) units, and the standard base was 1 January 1900, UT. In July 1999 the extended TODC clock was announced, which ...

    Real-time clocks are electronic devices designed to provide system time, and thereby wall-clock time, to a computer system. (Contrast this with clock signals , designed to provide timing for electronics themselves.)
