DESCRIPTION

14       timedatex  is a D-Bus service that implements the org.freedesktop.time‐
15       date1 interface. It can be used to read and set the system  clock,  the
16       real-time  clock  (RTC),  the system timezone, and enable or disable an
17       NTP client installed on the system. It is a replacement  for  the  sys‐
18       temd-timedated service.
19
20       The  system clock is read and set with microsecond resolution, the pre‐
21       cision is limited mostly by D-Bus latency. When setting the clock to an
22       absolute time, a correction is applied for the time spent in the polkit
23       authorization check. The clock can be also  adjusted  precisely  by  an
24       offset.
25
26       The RTC is read with a resolution of one second. The hwclock program is
27       used to set the RTC with a high precision, update the estimated  drift,
28       and change the UTC/LOCAL setting.
29
30       The system timezone is set by creating symlink /etc/localtime to a file
31       in the /usr/share/zoneinfo directory.
32
33       NTP units that should be controlled by timedatex need to be  listed  in
34       text files in /etc/systemd/ntp-units.d and /usr/lib/systemd/ntp-units.d
35       directories.  The first valid unit from the files sorted by name can be
36       enabled/disabled  and started/stopped. Other NTP units will be disabled
37       and stopped.
