Unlike ntpd, it supports synchronizing the system clock via hardware timestamping (i.e. packet times on the network adapter), improving accuracy of time synchronization between machines on a LAN [4] – to the order of 70 nanoseconds (from asymmetry), [12] comparable to Precision Time Protocol. It also supports synchronization by manual input ...
More complete synchronization systems, although lacking NTP's data analysis and clock disciplining algorithms, include the Unix daemon timed, which uses an election algorithm to appoint a server for all the clients; [19] and the Digital Time Synchronization Service (DTSS), which uses a hierarchy of servers similar to the NTP stratum model.
systemd-timedated is a daemon that can be used to control time-related settings, such as the system time, system time zone, or selection between UTC and local time-zone system clock. It is accessible through D-Bus. [61] It was integrated in systemd version 30. timesyncd timesyncd is a client NTP daemon for synchronizing the system clock across ...
Synchronization and management of a PTP system is achieved through the exchange of messages across the communications medium. To this end, PTP uses the following message types. Sync, Follow_Up, Delay_Req and Delay_Resp messages are used by ordinary and boundary clocks and communicate time-related information used to synchronize clocks across ...
In a system with a central server, the synchronization solution is trivial; the server will dictate the system time. Cristian's algorithm and the Berkeley algorithm are potential solutions to the clock synchronization problem in this environment. In distributed computing, the problem takes on more complexity because a global time is not easily ...
A White Rabbit network may be used solely to provide timing and synchronization to a distributed electronic system, or be used to provide both timing and real-time data transfer. [2] [3] The White Rabbit Project focuses on: Sub-nanosecond accuracy: synchronization of more than 1000 nodes via fibre or copper connections of up to 10 km of length.

Cristian's algorithm (introduced by Flaviu Cristian in 1989) [1] is a method for clock synchronization which can be used in many fields of distributive computer science but is primarily used in low-latency intranets.
