Mannam, please tidy up your previous post to remove the duplicated post updates.
Do a web search for the following phrase. Lots of information out there.

It should explain a lot about NTP "reach" to you.
Try the following. Stop your ntpd. Set you system clock as close to the actual real time as possible. Then start ntpd with the -g option to do a one time initial synchronization and see what happens.

ntptrace
ntptrace(8) System Manager's Manual ntptrace(8)
NAME
ntptrace - trace a chain of NTP servers back to the primary source
SYNOPSIS
ntptrace [ -n ] [ -m maxhosts ] [ server ]
DESCRIPTION
ntptrace is a perl script that uses the ntpq utility program to follow the chain of NTP servers from a given host back to the primary time
source. For ntptrace to work properly, each of these servers must implement the NTP Control and Monitoring Protocol specified in RFC 1305
and enable NTP Mode 6 packets.
If given no arguments, ntptrace starts with localhost. Here is an example of the output from ntptrace:
% ntptrace
localhost: stratum 4, offset 0.0019529, synch distance 0.144135
server2ozo.com: stratum 2, offset 0.0124263, synch distance 0.115784
usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'
On each line, the fields are (left to right): the host name, the host stratum, the time offset between that host and the local host (as
measured by ntptrace; this is why it is not always zero for "localhost"), the host synchronization distance, and (only for stratum-1
servers) the reference clock ID. All times are given in seconds. Note that the stratum is the server hop count to the primary source, while
the synchronization distance is the estimated error relative to the primary source. These terms are precisely defined in RFC-1305.
OPTIONS
-n Turns off the printing of host names; instead, host IP addresses are given. This may be useful if a nameserver is down.
BUGS
This program makes no attempt to improve accuracy by doing multiple samples.
