Hi,
Plz find my comment inline below.
One more point, if we direct fired insert query, then it is working fine
but with application, it is showing problem.
Points at a configuration issue in the application.

What Postgres version?
GauravàPostgres Version 9.1
How was Postgres installed and on what OS?
GauravàSolaris x86

What is the application using to connect to the server, ODBC, JDBC, etc?
GauravàJDBC4
The Postgres JDBC driver?
Is there anything showing up in the application logs?
Is this going through something else, Tomcat for instance?

So once the application is restarted the timestamp offset never changes
or do you have to restart periodically to reset?
GauravàWe don’t change it manually(Don’t know if any mechanism provided
by Postgres itself ti reset it periodically)
I am not following. You start the application, it has timestamp issues,
you restart it, the issues go away.
So how do they come back, unless the application is restarted?
If there is something in either Postgres or the application causing a
restart, there should be something in the logs. Is there?

Can you show an example of an INSERT.
An example of an INSERT statement and the corresponding inserted row in
the table would go along way in helping to troubleshoot this.

Is that the actual setting from postgresql.conf?
GauravàYes it the actual settings.
There is not a timezone specified?
GauravàYes, no time zone is specified.
Forgot that Postgres did not start setting the timezone in
postgresql.conf until 9.2+

If you are interested in timezone(time) correctness this should be 'with
timezone'.
GauravàBut we don’t want with timezone, as requirement is without timezone
