Difference between timestamps with/without time zone in PostgreSQL
...m You complicate matters with the ::timestamptz. With that you convert the string to TIMESTAMP WITH TIME ZONE, and when that will be further converted to WITHOUT TIME ZONE, that will store the "wall calendar" day and wall clock time of that instant as seen from your session time zone (which is maybe...
