High Quality Content by WIKIPEDIA articles! Clock drift refers to several related phenomena where a clock does not run at the exact right speed compared to another clock. That is, after some time the clock "drifts apart" from the other clock. This phenomenon is also used for instance in computers to build random number generators. On the negative side, clock drift can be exploited by timing attacks. Normal clocks such as clocks at home and wristwatches usually drift compared to the actual time. That is why one must reset their time occasionally. Clocks often drift differently depending on their quality, the exact power they get from the battery, the surrounding temperature and other environmental variables. Thus the same clock can have different clock drift rates at different occasions.
