How to set a time?

[indyjonesnl]

$lodgingBusiness = Schema::lodgingBusiness()
  ->openingHours(
    Schema::openingHoursSpecification()
      ->dayOfWeek([Schema::dayOfWeek()::Monday])
      ->opens(new DateTime('09:00:00'))
      ->closes(new DateTime('17:00:00'))
  )
  ->checkinTime(new DateTime('14:00:00'))
  ->checkoutTime(new DateTime('11:00:00'))

This results in the current date + time being included in the output "opens":"2024-01-10T09:00:00+00:00","closes":"2024-01-10T17:00:00+00:00" and ..."checkinTime":"2024-01-10T14:00:00+00:00","checkoutTime":"2024-01-10T11:00:00+00:00"...

While the Schema should contain only the time, formatted as 14:30:00+08:00.

Can someone point me in the right direction?

That's a problem right now - Time, Date and DateTime schema.org types are all assigned the DateTimeInterface php type.

schema-org/generator/Parser/Tasks/ParseProperty.php

Lines 51 to 54 in 111488e

	case 'Date':
	case 'Time':
	case 'DateTime':
	return ['\DateTimeInterface'];

And the DateTimeInterface php type is always formatted as atom string.

schema-org/generator/templates/static/BaseType.php

Lines 124 to 126 in 111488e

	if ($property instanceof DateTimeInterface) {
	$property = $property->format(DateTime::ATOM);
	}

It would need some additional data passing from the spec parser to the payload serializer or some additional interfaces - which would have to be custom as php doesn't have specific date or time only interfaces.
The current workaround would be to call the underlying setProperty() method directly with a simple string.
