Eloquent Model saved to DB with day and month inverted - php

Question

I am trying to save my Laravel Eloquent model to the database.
All date properties are saved in wrong format to DB (even created_at and updated_at).
In example below, my updated_at has been renamed as S_MODDATE but it's still the "native" field.
Reading the date fields works fine.
Example
My date in PHP : 2021-12-07 (7th of December)
When saved to database : 2012-07-12 (12th of July)
When read again from database : 2012-07-12
Minimal example of my code :
$currentDatetime = new \DateTime();
Log::debug($currentDatetime->format("Y-m-d h:i:s")); // Looks correct
$approRecord = T_Appro::find($approvalId);
$approRecord->DATESTATUT = $currentDatetime;
DB::enableQueryLog();
$approRecord->save();
Log::debug(DB::getQueryLog());

Tested solutions
Add protected $dateFormat = 'Y-m-d H:i:s'; to my model
Add following code to my model
public function getDateFormat()
{
return 'Y-m-d H:i:s.v';
}
Set app.php timezone to Europe/Brussels
