+NTP POOL:
+
+        By default, timesyncd uses the Google NTP servers
+        time[1-4].google.com. They serve time that is not standards
+        compliant, and can be up to .5s off. Google does not
+        officially support these servers for the broader
+        audience. Distributions and vendors really should not ship
+        OSes or devices with these NTP servers configured. Instead,
+        please register your own vendor pool at ntp.org and make it
+        the built-in default by passing --with-ntp-servers= to
+        configure. Registering vendor pools is free:
+
+        http://www.pool.ntp.org/en/vendors.html
+
+        Again, if you ship your software or device with the default
+        NTP servers, then you will get served wrong time, and will
+        rely on services that might not be supported for long.
