Last updated on AUGUST 04, 2018

Applies to:

In SQL*Plus, the timezone is always changed to GMT, although the machine is located in EST timezone. It could be verified with the following query:

$sqlplus user/pswd@dbalias
SQL>select sessiontimezone from dual;

Executing this query from SQL*Developer, installed in the same machine in EST timezone, sends the right date and time from the EST timezone.
