 # @param package_name [Array[String]] Specifies the NTP package to manage. Default value: ['ntp'] (except on AIX and Solaris).
 # @param panic [Optional Integer[0]] Whether NTP should "panic" in the event of a very large clock skew. Applies only if `tinker` option set to true or if your environment is in a virtual machine. Default value: 0 if environment is virtual, undef in all other cases.
 # @param peers [Array[String]] List of NTP servers with which to synchronise the local clock.
+# @param pool [Array[String]] List of NTP server pools with which to synchronise the local clock.
 # @param preferred_servers [Array[String] Specifies one or more preferred peers. Puppet appends 'prefer' to each matching item in the `servers` array. Default value: [ ].
 # @param restrict [Array[String]] Specifies one or more `restrict` options for the NTP configuration. Puppet prefixes each item with 'restrict', so you need to list only the content of the restriction. Default value for most operating systems: '[default kod nomodify notrap nopeer noquery', '-6 default kod nomodify notrap nopeer noquery', '127.0.0.1', '-6 ::1']`. Default value for AIX systems: `['default nomodify notrap nopeer noquery', '127.0.0.1',]`.
 # @param servers [Array[String]] Specifies one or more servers to be used as NTP peers. Default value: varies by operating system.
