connman's NTP client can't be used if it's not managing the network interface so use systemd's timesyncd as we already build it. timesyncd is automatically configured to use the NTP servers provided by kernel ip config, if they are missing the default fallback NTP servers (currently the ones from Google) are used. Users can also provide timesyncd configuration files via /storage/.config/timesyncd.conf.d/ eg to change the (fallback) servers. Signed-off-by: Matthias Reichl <hias@horus.com>

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.
