It is NTP v3.

It is production NTP server, so being little more caution before changing anything.

In last part of message, it again reported same lost yesterday. Does it say that, that time is dragging behind by approx second and then NTP service reset it, to bring it back ? Or in absense of any diagnostic tool (like chrony), it is difficult to say this statement ?

Code:

net::ntp

Net::NTP(3pm)						User Contributed Perl Documentation					     Net::NTP(3pm)

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.
