PC's maintain time using internal hardware clock chips. In order to reduce costs, these components are relatively low-cost devices, notoriously prone to drift. Therefore, the system time on a collection of networked computers can drift away from each other at different rates. After a relatively short period of time, large differences between the system times of each computer will be unavoidable. Unsynchronised time on computers on a network can lead to many problems. This article discusses the importance of computer network time synchronisation and of having an accurate network time reference in an organisation.
