Clock synchronization

Clock synchronization is a problem from computer science and engineering which deals with the idea that internal clocks of several computers may be different. 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 consequence of rate differences and several solutions, some being more appropriate than others in certain contexts.
