Hello,

Thanks for your feedback. I/we agree that the used format is not ideal as a default to store dates and this is something we want to change in the future. We’re thinking of a column setting for editing where you can manually set the storage date format. Or maybe just change the format, but that would require some fallbacks for the older date formats.

The code where this logic is happening is
/classes/Editing/Model/CustomField/Date.php

But you might want to have a look at this specific hook.
https://www.admincolumns.com/documentation/filter-reference/acp-editing-save/

The hook is fired after the value is already stored by our plugin. But you can do another save action and store the value to the DB the way you like. You have the actual value at your disposal, including the $column object that you can use to do some conditionals, like checking for the custom field and doing a field type check.

Hi Dirk,

I totally agree on your last comment.
But only change the default would break a lot of installs that already with the old Ymd format.
So the default format has to be together with the new date format setting.

Thanks for pointing us to the out of date documentation.
I just updated the documentation.
