Net::NTP - Perl extension for decoding NTP server responses
use Net::NTP; my %response = get_ntp_response();
All this module does is send a packet to an NTP server and then decode the packet recieved into it's respective parts - as outlined in RFC1305 and RFC2030.
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 th information recieved 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.
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.
