##Overview

This module configures NTP servers on Windows machines.

##Module Description

This module requires the registry and stdlib modules that are found at their appropriate links.

This module configures the w32time service to use a standard time server (time.windows.com) or an array or custom time servers. It achieves this through registry entries.

##Usage

###Basic OS default example In this example the module will ensure the w32time service is running and syncronizing with the Microsoft default time.windows.com server:

  include 'winntp'

###Example of setting the time servers to two custom addresses In this example the two servers that are passed as variables will be set on all nodes with this classification applied:

  class { 'winntp':
    servers => ['time.nist.gov', 'pool.ntp.org'],
  }

##Parameters

The following parameters are available in the winntp class:

###servers (optional) Specifies the time servers to be set.
Valid Input: Array of strings Default: "time.windows.com"

###special_poll_interval (optional) Specifies the poll time in seconds.
Valid Input: integer Default: 900

###max_pos_phase_correction (optional) Specifies the max positive (forward) sample time a server can accept in seconds.
Valid Input: integer Default: 54000

###max_neg_phase_correction (optional) Specifies the max negetive (backwards) sample time a server can accept in seconds.
Valid Input: integer Default: 54000

###purge_unmanaged_servers (optional) Purge servers not specified by this module if they exist. Valid Input: boolean Default: true

##Limitations The module is compatiable with Windows machines.
