Certain migration timestamp formats not working

Hi there.


On my GNU/Linux machine I have installed XAMPP 8.1.12 and a fresh Composer installation of CodeIgniter 4.2.11 (both latest to this moment). I am successfully connected to the database.

There is a timestamp format setting in app/Config/Migrations.php . The default setting works fine:

PHP Code:

public $timestampFormat = 'Y-m-d-His_'; 


If I change the format in a way that "His" have characters between the letters, it will not find any migration:

PHP Code:

public $timestampFormat = 'Y-m-d-H-i-s_'; 


Could anyone confirm this bug? I am pretty sure it is not a feature.
