NAME
systemd-timedated.service, systemd-timedated - Time and date bus
mechanism
SYNOPSIS
systemd-timedated.service
/usr/lib/systemd/systemd-timedated
DESCRIPTION
systemd-timedated.service is a system service that may be used as a
mechanism to change the system clock and timezone, as well as to
enable/disable network time synchronization. systemd-timedated is
automatically activated on request and terminates itself when it is
unused.
The tool timedatectl(1) is a command line client to this service.
systemd-timedated currently offers access to the following four
settings:
o The system time
o The system timezone
o A boolean controlling whether the system RTC is in local or UTC
timezone
o Whether the time synchronization service is enabled/started or
disabled/stopped, see next section.
See org.freedesktop.timedate1(5) and org.freedesktop.LogControl1(5) for
information about the D-Bus API.
LIST OF NETWORK TIME SYNCHRONIZATION SERVICES
systemd-timedated will look for files with a ".list" extension in
ntp-units.d/ directories. Each file is parsed as a list of unit names,
one per line. Empty lines and lines with comments ("#") are ignored.
Files are read from /usr/lib/systemd/ntp-units.d/ and the corresponding
directories under /etc/, /run/, /usr/local/lib/. Files in /etc/
override files with the same name in /run/, /usr/local/lib/, and
/usr/lib/. Files in /run/ override files with the same name under
/usr/. Packages should install their configuration files in /usr/lib/
(distribution packages) or /usr/local/lib/ (local installs).
Example 1. ntp-units.d/ entry for systemd-timesyncd
# /usr/lib/systemd/ntp-units.d/80-systemd-timesync.list
systemd-timesyncd.service
If the environment variable $SYSTEMD_TIMEDATED_NTP_SERVICES is set,
systemd-timedated will parse the contents of that variable as a
colon-separated list of unit names. When set, this variable overrides
the file-based list described above.
Example 2. An override that specifies that chronyd should be used if
available
SYSTEMD_TIMEDATED_NTP_SERVICES=chronyd.service:systemd-timesyncd.service
