NAME

       Net::NTP - Perl extension for decoding NTP server responses

SYNOPSIS

         use Net::NTP qw(get_ntp_response);
         my %response = get_ntp_response();

ABSTRACT

       All this module does is send a packet to an NTP server and then decode the packet received
       into it's respective parts - as outlined in RFC1305 and RFC2030.

DESCRIPTION

       This module exports a single method (get_ntp_response) and returns an associative array
       based upon RFC1305 and RFC2030.  The response from the server is "humanized" to a point
       that further processing of the information received from the server can be manipulated.
       For example: timestamps are in epoch, so one could use the localtime function to produce
       an even more "human" representation of the timestamp.

   EXPORT
       get_ntp_response(<server>, <port>);

       This module exports a single method - get_ntp_response.  It takes the server as the first
       argument (localhost is the default) and port to send/recieve the packets (ntp or 123 bu
       default).  It returns an associative array of the various parts of the packet as outlined
       in RFC1305.  It "normalizes" or "humanizes" various parts of the packet.  For example: all
       the timestamps are in epoch, NOT hexidecimal.
