使用oracle数据库的Yii1 findByPk现在返回日期的其他格式

Question

I am having an issue with oracle 11g and yii 1.1 when retrieving dates:

I am having an initSQL as follows:

                    "ALTER SESSION SET NLS_DATE_FORMAT='dd-mm-yyyy hh24:mi:ss'",
                    'ALTER SESSION SET NLS_COMP=ANSI',
                    'ALTER SESSION SET NLS_COMP=LINGUISTIC',
                    'ALTER SESSION SET NLS_SORT=GENERIC_BASELETTER',
                    'ALTER SESSION SET NLS_SORT=BINARY_AI',

but when the application returns a date through a findByPk() for example it returns it in 'dd-MMM-yy' format for example 25-MAY-19, this happened when changing from one server to another but connecting to the same database, but right now I am unable to find which config param is causing this. Any Ideas
