Starting with Debian jessie, "ntp" package is no longer required to synchronize your server using NTP protocol. New "systemd-timesyncd" service is the prefered method.
This module :
- Removes "ntp" package
- Creates "/etc/systemd/timesyncd.conf" file with "www.ntp.org" time references
- Starts and enables "systemd-timesyncd"
include ::timesyncd
On Debian 8.x (jessie) only !
