+############
+
+|CLOSIA| uses the `systemd-timesyncd.service` daemon to synchronize time.
+
+This section provides instructions to reset the time in your |CL| system when
+the default :abbr:`NTP (Network Time Protocol)` servers cannot be reached.
+
+#. 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 :file:`/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.
+
+Congratulations! You have successfully set up the time in your |CL| system.
+
+Further, you are now able to change the time and timezone from your |CL|
+desktop. The :guilabel:`Date & Time` options are located in the
+:guilabel:`Settings` application under the :guilabel:`Details`
+tab.
