DetailView: minutes instead of month shown (datetime)

Yii 2.0 General Discussions

Hello!

In on of my tables I have a column last_modified created as DATETIME. So one entry there e.g. is 2014-10-15 07:36:03.

Now I try to format the output, but is does not work as I would like to have it.


<?= DetailView::widget([

        'model' => $model,

        'attributes' => [

            ...

            'last_modified',

            [

                'attribute' => 'last_modified',

                'format' => ['datetime', 'Y-m-d'],

            ],            

            ...

        ],

    ]) ?>

The first output is 2014-10-15 07:36:03 as expected.

The second output is 2014-36-15 but I was expecting 2014-10-15.

I get the same output with


'format' => ['date', 'Y-m-d'],

.

For me it looks like there was shown year-minute-day but I would like to have the month instead. What do I not see here and how can I get my desired output?

Thanks in advance!

Best regards,

Heiko
