Postgres create table timestamp with timezone

I would like to define a best practice for storing timestamps in my Postgres database in the context of a multi- timezone project. PostgreSQL does not store any timezone data with the timestamptz value. Let’s take a look at an example of using the timestamp and timestamptz to have a better understanding of how the PostgresQL handles them.

First, create a table that consists of both timestamp the timestamptz columns. I have a server that has a column timestamp without timezone. I select column with timestamp it will show server timestamp with timezone. But If I move the data from EST to Central will the timestamp with timezone be correct?

Or will it just not make the adjustment? CREATE TABLE will create a new, initially empty table in the current database. The table will be owned by the user issuing the command.
