Everyday clocks such as wristwatches have finite precision. Eventually they require correction to remain accurate. The rate of drift depends on the clock's quality, sometimes the stability of the power source, the ambient temperature, and other subtle environmental variables. Thus the same clock can have different drift rates at different ...
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.

Clock recovery addresses this problem by embedding clock information into the data stream, allowing the transmitter's clock timing to be determined. This normally takes the form of short signals inserted into the data that can be easily seen and then used in a phase-locked loop or similar adjustable oscillator to produce a local clock signal ...
In digital transmission, bit slip is the loss or gain of a bit or bits, caused by clock drift – variations in the respective clock rates of the transmitting and receiving devices. One cause of bit slip is overflow of a receive buffer that occurs when the transmitter's clock rate exceeds that of the receiver.
[1] [2] The mismatch between the two systems' clocks is known as the plesiochronous difference. In general, plesiochronous systems behave similarly to synchronous systems , except they must employ some means in order to cope with "sync slips", which will happen at intervals due to the plesiochronous nature of the system.
Hence the satellites' clocks gain approximately 38,640 nanoseconds a day or 38.6 μs per day due to relativistic effects in total. In order to compensate for this gain, a GPS clock's frequency needs to be slowed by the fraction: 5.307 × 10 −10 – 8.349 × 10 −11 = 4.472 × 10 −10
