Note that the column is of type timestamp, which _doesn't_ have a time
zone. You probably want
time_stamp timestamp with time zone DEFAULT ('now'::text)::timestamp with time zone

It doesn't because the time zone information is not being stored due to
the datatype issue I mentioned above.
Note: the time zone is not actually stored. What actually happens is
that the value is "rotated" to GMT and stored as a GMT value, and then
when you extract it from the database it is "rotated" to the current
TimeZone for display. If you need to store what time zone a value "is
in" you need to store that information in a separate column.
