How do I create a time range form field?

Question

Is there any way to add time range input fields in a form, for example using code similar to the following one?

$form['notification_hours'] = array(
  '#type' => 'time_range', // type time_range doesn't work
  '#title' => $this->t('Notification hours:'),
  '#default_value' => $config->get('ecc_general.notification_hours'),
  '#description' => $this->t('what are the hours that messages should not be sent?'),
);

I have tried the Time Range and and Time Field modules. I'm able to add the time range field, but I failed to programmatically create it.

Haven't tested this but if you install time field module you then could do this to simulate a range:

$form['from'] = [
  '#type' => 'time',
  '#title' => 'from',
];
$form['to'] = [
  '#type' => 'time',
  '#title' => 'to',
];
