TIMEDATECTL(1)			  timedatectl			TIMEDATECTL(1)

NAME
       timedatectl - Control the system time and date

SYNOPSIS
       timedatectl [OPTIONS...] {COMMAND}

DESCRIPTION
       timedatectl may be used to query and change the system clock and its
       settings.

OPTIONS
       The following options are understood:

       -h, --help
	   Prints a short help text and exits.

       --version
	   Prints a short version string and exits.

       --no-pager
	   Do not pipe output into a pager.

       --no-ask-password
	   Do not query the user for authentication for privileged operations.

       -P, --privileged
	   Acquire privileges via PolicyKit before executing the operation.

       -H, --host
	   Execute the operation remotely. Specify a hostname, or username and
	   hostname separated by "@", to connect to. This will use SSH to talk
	   to a remote system.

       --adjust-system-clock
	   If set-local-rtc is invoked and this option is passed, the system
	   clock is synchronized from the RTC again, taking the new setting
	   into account. Otherwise, the RTC is synchronized from the system
	   clock.

       The following commands are understood:

       status
	   Show current settings of the system clock and RTC.

       set-time [TIME]
	   Set the system clock to the specified time. This will also update
	   the RTC time accordingly. The time may be specified in the format
	   "2012-10-30 18:17:16".

       set-timezone [TIMEZONE]
	   Set the system time zone to the specified value. Available
	   timezones can be listed with list-timezones. If the RTC is
	   configured to be in the local time, this will also update the RTC
	   time. This call will alter the /etc/localtime symlink. See
	   localtime(5) for more information.

       list-timezones
	   List available time zones, one per line. Entries from the list can
	   be set as the system timezone with set-timezone.

       set-local-rtc [BOOL]
	   Takes a boolean argument. If "0", the system is configured to
	   maintain the RTC in universal time. If "1", it will maintain the
	   RTC in local time instead. Note that maintaining the RTC in the
	   local timezone is not fully supported and will create various
	   problems with time zone changes and daylight saving adjustments. If
	   at all possible, keep the RTC in UTC mode. Note that invoking this
	   will also synchronize the RTC from the system clock, unless
	   --adjust-system-clock is passed (see above). This command will
	   change the 3rd line of /etc/adjtime, as documented in hwclock(8).

       set-ntp [BOOL]
	   Takes a boolean argument. Controls whether NTP based network time
	   synchronization is enabled (if available).

EXIT STATUS
       On success, 0 is returned, a non-zero failure code otherwise.

ENVIRONMENT
       $SYSTEMD_PAGER
	   Pager to use when --no-pager is not given; overrides $PAGER.
	   Setting this to an empty string or the value "cat" is equivalent to
	   passing --no-pager.

EXAMPLES
       Show current settings:

	   $ timedatectl
		 Local time: Fri, 2012-11-02 09:26:46 CET
	     Universal time: Fri, 2012-11-02 08:26:46 UTC
		   RTC time: Fri, 2012-11-02 08:26:45
		   Timezone: Europe/Warsaw
		 UTC offset: +0100
		NTP enabled: no
	   NTP synchronized: no
	    RTC in local TZ: no
		 DST active: no
	    Last DST change: CEST → CET, DST became inactive
			     Sun, 2012-10-28 02:59:59 CEST
			     Sun, 2012-10-28 02:00:00 CET
	    Next DST change: CET → CEST, DST will become active
			     the clock will jump one hour forward
			     Sun, 2013-03-31 01:59:59 CET
			     Sun, 2013-03-31 03:00:00 CEST

       Enable an NTP daemon (chronyd):

	   $ timedatectl set-ntp true
	   ==== AUTHENTICATING FOR org.freedesktop.timedate1.set-ntp ===
	   Authentication is required to control whether network time synchronization shall be enabled.
	   Authenticating as: user
	   Password: ********
	   ==== AUTHENTICATION COMPLETE ===

	   $ systemctl status chronyd.service
	   chronyd.service - NTP client/server
		     Loaded: loaded (/usr/lib/systemd/system/chronyd.service; enabled)
		     Active: active (running) since Fri, 2012-11-02 09:36:25 CET; 5s ago
	   ...
