How to use single_datetime in custom form API

I found the solution

$form['dob'] = [
'#title' => 'Date of Birth',
'#type' => 'textfield',
'#time' => TRUE,
'#weight' => -10,
'#attributes' => [
'data-hour-format' => '24h',
'data-allow-times' => '5',
'data-first-day' => '0',
'data-disable-days' => [],
'data-inline' => '0',
'data-datetimepicker-theme' => 'default',
'data-single-date-time' => 'datetime',
],
];
$form['#attached']['library'][] = 'single_datetime/datetimepicker';
$form['#attributes']['autocomplete'] = 'off';

$form['submit'] = [
'#type' => 'submit',
'#value' => 'Submit',
];
