Hi @pikhovkin - Can you provide any more details and/or code that you're using? Looking at the tests, are you doing anything different, or can you create a test that replicates what you're seeing?

In the tests, here's the DATE attribute being created - are you doing it differently?

Here's the test that stores datetime values in the Attribute, along with saving the model successfully.

Hi, @Dresdn! I use admin site to save an attribute of "date" type.

  File ".../python3.10/site-packages/django/forms/fields.py", line 530, in to_python
    result = parse_datetime(value.strip())

The value contains ['2022-10-10', '08:55:05']
