TYPO3 Core

For example the styleguide field

        'inputdatetime_11' => [
            'label' => 'inputdatetime_11',
            'description' => 'eval=datetime, default=0, range.lower=1627208536',
            'config' => [
                'type' => 'datetime',
                'format' => 'date',
                'default' => 0,
                'range' => [
                    'lower' => 1627208536,
                ],
            ],
        ],

Try to set any date. The field can't be saved. FormEngine validation complains the value is incorrect.

Does not happen in TYPO3 v11.
