Problem with TIMESTAMP WITH TIME ZONE

I need to copy a table from PostgreSQL to Oracle.
The source table contains a field with TIMESTAMP WITH TIME ZONE as type.

In Oracle too I have set TIMESTAMP WITH TIME ZONE as type for this attribute.

The problem is that when I copy the data from the source table, the destination table contains the timestamp converted into my local time zone. For example:


Instead, I want to have the same time zone in the source and in the destination table.

I've also tried using a select values step between source and destination, setting the source time zone as "Date Time Zone", but this didn't worked.

Any idea?
