Show the data into EST timezone from UTC timezone in laravel

My created_at and updated_at column is inserted in UTC timezone. Now I want to show the data according to "america/chicago" timezone. I am using the Carbon library to get the result.

Below is the code I have written to fetch the information from database.

    public function getAllUsers(){
        $users =  BaseUserModel::
        select('id', 'email', 'created_at')
            ->whereDate(
                'created_at',
                '=',
                Carbon::today('america/chicago')
            )
            ->orderBy('created_at', 'desc')
            ->limit(5)->get();
        return $users;
    }

Attached database entry with UTC time. Now when I am trying to execute the query, getting only one output(2018-10-03 15:27:18). But my expected output should come both date in "america/timezone".
