module: appliance_ntp
short_description: Set NTP servers
description: Set NTP servers. This method updates old NTP servers from configuration
    and sets the input NTP servers in the configuration. If NTP based time synchronization
    is used internally, the NTP daemon will be restarted to reload given NTP configuration.
    In case NTP based time synchronization is not used, this method only replaces
    servers in the NTP configuration.

    servers:
