+Set the time
+############
+
+In |CL|, it is not possible to set the time manually, via `timedatectl`
+nor `RTC` mode. |CLOSIA| instead uses the `systemd-timesyncd.service` daemon
+to synchronize time.
+
+This section provides instructions to reset the time in your |CL| system when
+the default network time protocol (NTP) servers cannot be reached. The default
+NTP servers are configured as
+time1.google.com, time2.google.com, time3.google.com, and time4.google.com.
+
+#. Install the `sysadmin-basic` bundle:
+
+   .. code-block:: console
+
+      swupd bundle-add sysadmin-basic
+
+#. Set your timezone (this example uses Los Angeles).
+
+   .. code-block:: console
+
+      timedatectl set-timezone America/Los_Angeles
+
+   .. note::
+      To see a list of timezones, enter:
+      `timedatectl list-timezones | grep <locale>`
+
+#. Create a `/etc/systemd/` directory.
+
+   .. code-block:: console
+
+      mkdir -p /etc/systemd/
+
+#. Create a new file named :file:`/etc/systemd/timesyncd.conf` and enter the
+   following:
+
+   .. code-block:: .conf
+
+      [Time]
+      NTP=<Preferred Server>
+      FallbackNTP=<backup server 1> <backup server 2>
+
+#. Enable the `systemd-timesyncd` service.
+
+   .. code-block:: console
+
+      timedatectl set-ntp true
+
+.. note::
+
+   Use the :command:`timedatectl status` command to check the service status.
+   To restart the `timesyncd` daemon, enter :command:`systemctl restart systemd-timesyncd`
+   into your terminal emulator.
