systemd-timesyncd.service(8) is a system service that may be used to synchronize the local system clock with a remote Network Time Protocol (NTP) server. This page describes the D-Bus interface.
The service exposes the following interfaces on the Manager object on the bus:
node /org/freedesktop/timesync1 {
interface org.freedesktop.timesync1.Manager {
methods:
SetRuntimeNTPServers(in as runtime_servers);
properties:
readonly as LinkNTPServers = ['...', ...];
readonly as SystemNTPServers = ['...', ...];
readonly as RuntimeNTPServers = ['...', ...];
readonly as FallbackNTPServers = ['...', ...];
@org.freedesktop.DBus.Property.EmitsChangedSignal("false")
readonly s ServerName = '...';
@org.freedesktop.DBus.Property.EmitsChangedSignal("false")
readonly (iay) ServerAddress = ...;
@org.freedesktop.DBus.Property.EmitsChangedSignal("const")
readonly t RootDistanceMaxUSec = ...;
@org.freedesktop.DBus.Property.EmitsChangedSignal("const")
readonly t PollIntervalMinUSec = ...;
@org.freedesktop.DBus.Property.EmitsChangedSignal("const")
readonly t PollIntervalMaxUSec = ...;
@org.freedesktop.DBus.Property.EmitsChangedSignal("false")
readonly t PollIntervalUSec = ...;
readonly (uuuuittayttttbtt) NTPMessage = ...;
@org.freedesktop.DBus.Property.EmitsChangedSignal("false")
readonly x Frequency = ...;
};
interface org.freedesktop.DBus.Peer { ... };
interface org.freedesktop.DBus.Introspectable { ... };
interface org.freedesktop.DBus.Properties { ... };
};
Provides information about the manager.
Example 1. Introspect org.freedesktop.timesync1.Manager on the bus
$ gdbus introspect --system \ --dest org.freedesktop.timesync1 \ --object-path /org/freedesktop/timesync1
These D-Bus interfaces follow m[blue]the usual interface versioning guidelinesm[][1].
