    - A list of up to 4 alternate NTP servers. These may include IPv4,
      IPv6 or FQDNs. Invalid IP addresses will cause the module to fail.
      No validation is performed for FQDNs.
    - If more than 4 servers are provided, only the first 4 unique
      nameservers will be used.
    - if no servers are given a default of I(0.pool.ntp.org) will be used.
