+# Please make sure the paths below are correct.
+# Alternatively you can put them in $0.conf, meaning if you've named
+# this script ntp-client then it must go in ntp-client.conf .
+#
+# If you are unsure, which to set, run this script and make sure that
+# the JSON output variables match that in "ntpq -c rv".
+#
+# `--ntpsec` for ntpsec, `--systemd-timesyncd` for `systemd-timesyncd`
