Clock skew vs clock drift

Clock drift refers to several related phenomena where a clock does not run at exactly the same rate as a reference clock. That is, after some time the clock "drifts apart" or gradually desynchronizes from the other clock. All clocks are subject to drift, causing eventual divergence unless resynchronized. In particular, the drift … See more 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 … See more Computer programs often need high quality random numbers, especially for cryptography. There are several similar ways clock drift can … See more • Bit slip • Clock skew • Effects of relativity on GPS • Injection locking See more Atomic clocks are very precise and have nearly no clock drift. Even the Earth's rotation rate has more drift and variation in drift than an atomic … See more As Einstein predicted, relativistic effects can also cause clock drift due to time dilation. This is because there is no fixed universal time, time being … See more In 2006, a side channel attack was published that exploited clock skew based on CPU heating.
