This module can be used as part of the bootstrapping of a BIG-IP. It allows one to configure the various NTP settings that are part of a BIG-IP.
Tests for this module can be found here https://github.com/F5Networks/f5-ansible/blob/master/roles/__bigip_device_ntp/tasks/main.yaml Platforms this was tested on are 11.6.0 12.0.0 12.1.0 12.1.0 HF1pull/18777/head
