NAME
|
|
timesyncd.conf, timesyncd.conf.d - Network Time Synchronization
|
|
configuration files
|
|
|
|
SYNOPSIS
|
|
/etc/systemd/timesyncd.conf
|
|
|
|
/etc/systemd/timesyncd.conf.d/*.conf
|
|
|
|
/run/systemd/timesyncd.conf.d/*.conf
|
|
|
|
/usr/lib/systemd/timesyncd.conf.d/*.conf
|
|
|
|
DESCRIPTION
|
|
These configuration files control NTP network time synchronization. See
|
|
systemd.syntax(5) for a general description of the syntax.
|
|
|
|
CONFIGURATION DIRECTORIES AND PRECEDENCE
|
|
The default configuration is defined during compilation, so a
|
|
configuration file is only needed when it is necessary to deviate from
|
|
those defaults. By default, the configuration file in /etc/systemd/
|
|
contains commented out entries showing the defaults as a guide to the
|
|
administrator. This file can be edited to create local overrides.
|
|
|
|
When packages need to customize the configuration, they can install
|
|
configuration snippets in /usr/lib/systemd/*.conf.d/. Files in /etc/
|
|
are reserved for the local administrator, who may use this logic to
|
|
override the configuration files installed by vendor packages. The main
|
|
configuration file is read before any of the configuration directories,
|
|
and has the lowest precedence; entries in a file in any configuration
|
|
directory override entries in the single configuration file. Files in
|
|
the *.conf.d/ configuration subdirectories are sorted by their filename
|
|
in lexicographic order, regardless of which of the subdirectories they
|
|
reside in. When multiple files specify the same option, for options
|
|
which accept just a single value, the entry in the file with the
|
|
lexicographically latest name takes precedence. For options which
|
|
accept a list of values, entries are collected as they occur in files
|
|
sorted lexicographically. It is recommended to prefix all filenames in
|
|
those subdirectories with a two-digit number and a dash, to simplify
|
|
the ordering of the files.
|
|
|
|
To disable a configuration file supplied by the vendor, the recommended
|
|
way is to place a symlink to /dev/null in the configuration directory
|
|
in /etc/, with the same filename as the vendor configuration file.
|
|
|
|
OPTIONS
|
|
The following settings are configured in the "[Time]" section:
|
|
|
|
NTP=
|
|
A space-separated list of NTP server host names or IP addresses.
|
|
During runtime this list is combined with any per-interface NTP
|
|
servers acquired from systemd-networkd.service(8).
|
|
systemd-timesyncd will contact all configured system or
|
|
per-interface servers in turn until one is found that responds.
|
|
When the empty string is assigned, the list of NTP servers is
|
|
reset, and all assignments prior to this one will have no effect.
|
|
This setting defaults to an empty list.
|
|
|
|
FallbackNTP=
|
|
A space-separated list of NTP server host names or IP addresses to
|
|
be used as the fallback NTP servers. Any per-interface NTP servers
|
|
obtained from systemd-networkd.service(8) take precedence over this
|
|
setting, as do any servers set via NTP= above. This setting is
|
|
hence only used if no other NTP server information is known. When
|
|
the empty string is assigned, the list of NTP servers is reset, and
|
|
all assignments prior to this one will have no effect. If this
|
|
option is not given, a compiled-in list of NTP servers is used
|
|
instead.
|
|
|
|
RootDistanceMaxSec=
|
|
Maximum acceptable root distance. Takes a time value (in seconds).
|
|
Defaults to 5 seconds.
|
|
|
|
PollIntervalMinSec=, PollIntervalMaxSec=
|
|
The minimum and maximum poll intervals for NTP messages. Each
|
|
setting takes a time value (in seconds). PollIntervalMinSec= must
|
|
not be smaller than 16 seconds. PollIntervalMaxSec= must be larger
|
|
than PollIntervalMinSec=. PollIntervalMinSec= defaults to 32
|
|
seconds, and PollIntervalMaxSec= defaults to 2048 seconds.
