Purpose:

To change datetime format from default H:i d-m-Y to customer format H:i d.m.Y

In TCA:
'field_name' => array(
'label' => 'Label name',
'config' => array(
'type' => 'input',
'size' => 20,
'max' => 20,
'eval' => 'datetime'
)
)

Set [SYS][ddmmyy] = d.m.Y and it shows in the list module.
But it does not display d.m.Y into the input field when clicking on datepicker icon.
