Oracle uses an internal date/time representation, and the way it's displayed is determined by the sessions NLS_DATE_FORMAT setting, eg ALTER SESSION SET NLS_DATE_FORMAT='YYYYMMDDHH24MISS';

SET SESSION
AUTHORIZATION(7) SQL Commands SET SESSION AUTHORIZATION(7)
NAME
SET SESSION AUTHORIZATION - set the session user identifier and the current user identifier of the current session
SYNOPSIS
SET [ SESSION | LOCAL ] SESSION AUTHORIZATION username
SET [ SESSION | LOCAL ] SESSION AUTHORIZATION DEFAULT
RESET SESSION AUTHORIZATION
DESCRIPTION
This command sets the session user identifier and the current user identifier of the current SQL session to be username. The user name can
be written as either an identifier or a string literal. Using this command, it is possible, for example, to temporarily become an unprivi-
leged user and later switch back to being a superuser.
The session user identifier is initially set to be the (possibly authenticated) user name provided by the client. The current user identi-
fier is normally equal to the session user identifier, but might change temporarily in the context of SECURITY DEFINER functions and simi-
lar mechanisms; it can also be changed by SET ROLE [set_role(7)]. The current user identifier is relevant for permission checking.
The session user identifier can be changed only if the initial session user (the authenticated user) had the superuser privilege. Other-
wise, the command is accepted only if it specifies the authenticated user name.
The SESSION and LOCAL modifiers act the same as for the regular SET [set(7)] command.
The DEFAULT and RESET forms reset the session and current user identifiers to be the originally authenticated user name. These forms can be
executed by any user.
NOTES
SET SESSION AUTHORIZATION cannot be used within a SECURITY DEFINER function.
EXAMPLES
SELECT SESSION_USER, CURRENT_USER;
session_user | current_user
--------------+--------------
peter | peter
SET SESSION AUTHORIZATION 'paul';
SELECT SESSION_USER, CURRENT_USER;
session_user | current_user
--------------+--------------
paul | paul
COMPATIBILITY
The SQL standard allows some other expressions to appear in place of the literal username, but these options are not important in practice.
PostgreSQL allows identifier syntax ("username"), which SQL does not. SQL does not allow this command during a transaction; PostgreSQL does
not make this restriction because there is no reason to. The SESSION and LOCAL modifiers are a PostgreSQL extension, as is the RESET syn-
tax.
The privileges necessary to execute this command are left implementation-defined by the standard.
