To work, your network infrastructure needs a single accurate time reference. All IT equipment has an embedded hardware or software clock which is used by the equipment to timestamp files, transactions, events, images, etc. This internal clock drifts like any ordinary watch. It becomes an issue when these devices are connected to a network and share common resources such as file systems.
The integrity of any file system depends on the names and dates of the files, including information on the date of creation, last access, last archive and last modification. In a distributed file sharing system, a master file is kept by an NFS (Network File System) server, for use by remote clients.
