+                system service that may be used to synchronize the
+                local system clock with a remote Network Time Protocol
+                server. It also saves the local time to disk every
+                time the clock has been synchronized and uses this to
+                possibly advance the system realtime clock on
+                subsequent reboots to ensure it
+                monotonically advances even if the system lacks a
+                battery-buffered RTC chip.</para>
+
+                <para>The NTP servers contacted are determined from
+                the global settings in
+                <citerefentry><refentrytitle>timesyncd.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
+                the per-link static settings in
+                <filename>.network</filename> files, and the per-link
+                dynamic settings received over DHCP. See
