-NTP
-###
-
-:abbr:`NTP (Network Time Protocol`) is a networking protocol for clock
-synchronization between computer systems over packet-switched, variable-latency
-data networks. In operation since before 1985, NTP is one of the oldest Internet
-protocols in current use.
-
-NTP is intended to synchronize all participating computers to within a few
-milliseconds of :abbr:`UTC (Coordinated Universal Time)`. It uses the
-intersection algorithm, a modified version of Marzullo's algorithm, to select
-accurate time servers and is designed to mitigate the effects of variable
-network latency. NTP can usually maintain time to within tens of milliseconds
-over the public Internet, and can achieve better than one millisecond accuracy
-in local area networks under ideal conditions. Asymmetric routes and network
-congestion can cause errors of 100 ms or more.
-
-The protocol is usually described in terms of a client-server model, but can as
-easily be used in peer-to-peer relationships where both peers consider the other
-to be a potential time source. Implementations send and receive timestamps using
-:abbr:`UDP (User Datagram Protocol)` on port number 123.
-
-NTP supplies a warning of any impending leap second adjustment, but no
-information about local time zones or daylight saving time is transmitted.
-
-The current protocol is version 4 (NTPv4), which is a proposed standard as
-documented in :rfc:`5905`. It is backward compatible with version 3, specified
-in :rfc:`1305`.

-Configuration
-=============
-
-.. cfgcmd:: set system ntp server <address>
-
-   Configure one or more servers for synchronisation. Server name can be either
-   an IP address or :abbr:`FQDN (Fully Qualified Domain Name)`.
-
-   There are 3 default NTP server set. You are able to change them.
-
-   * ``0.pool.ntp.org``
-   * ``1.pool.ntp.org``
-   * ``2.pool.ntp.org``
-
-.. cfgcmd:: set system ntp server <address> <noselect | pool | preempt | prefer>
-
-   Configure one or more attributes to the given NTP server.
-
-   * ``noselect`` marks the server as unused, except for display purposes. The
-     server is discarded by the selection algorithm.
-
-   * ``pool`` mobilizes persistent client mode association with a number of
-     remote servers.
-
-   * ``preempt`` a preemptable association is expendable.
-
-   * ``prefer`` marks the server as preferred. All other things being equal,
-     this host will be chosen for synchronization among a set of correctly
-     operating hosts.
-
-.. cfgcmd:: set system ntp listen-address <address>
-
-   NTP process will only listen on the specified IP address. You must specify
-   the `<address>` and optionally the permitted clients. Multiple listen
-   addresses can be configured.
-
-.. cfgcmd:: set system ntp allow-clients address <address>
-
-   List of networks or client addresses permitted to contact this NTP server.
-
-   Multiple networks can be configured.
-
-.. cfgcmd:: set system ntp vrf <name>
-
-  Specify name of the :abbr:`VRF (Virtual Routing and Forwarding)` instance.
