  <title>Network Time Protocol daemon (version 4)</title>
3
  <description>The Network Time Protocol (NTP) is used to synchronize the time of a
4
computer client or server to another server or reference time source, such
5
as a radio or satellite receiver or modem. It provides client accuracies
6
typically within a millisecond on LANs and up to a few tens of milliseconds
7
on WANs relative to a primary server synchronized to Coordinated
8
Universal Time (UTC) via a Global Positioning Service (GPS) receiver, for
9
example. Typical NTP configurations utilize multiple redundant servers and
10
diverse network paths, to achieve high accuracy and reliability.
11
Some configurations include cryptographic authentication to prevent
12
accidental or malicious protocol attacks.
13
ntpd is an operating system daemon which sets and maintains the system
14
time-of-day synchronized with Internet standard time servers. ntpd is a
15
complete implementation of the Network Time Protocol (NTP) version 4, but
16
also retains compatibility with version 3, as defined by RFC-1305, and version
17
1 and 2, as defined by RFC-1059 and RFC-1119, respectively. ntpd does
18
most computations in 64-bit floating point arithmetic and does relatively
19
clumsy 64-bit fixed point operations only when necessary to preserve the
20
ultimate precision, about 232 picoseconds. While the ultimate precision is not
21
achievable with ordinary workstations and networks of today, it may be
22
required with future nanosecond CPU clocks and gigabit LANs.
23
The daemon can operate in any of several modes, including symmetrical
24
active/passive, client/server broadcast/multicast, and manycast. A
25
broadcast/multicast or manycast client can discover remote servers, compute
26
server-client propagation delay correction factors, and configure itself
27
automatically. This makes it possible to deploy a fleet of workstations without
28
specifying configuration details specific to the local environment.
29
Ordinarily, ntpd reads the ntp.conf configuration file at start-up time
30
to determine the synchronization sources and operating modes. It is also
31
possible to specify a working, although limited, configuration entirely on the
32
command line, obviating the need for a configuration file. This may be
33
particularly appropriate when the local host is to be configured as a
34
broadcast/multicast client or manycast client, with all peers being determined
35
by listening to broadcasts at run time.
36
Various internal ntpd variables can be displayed and configuration options
37
altered while the daemon is running using the ntpq and ntpdc utility
38
programs.
