VideoObject Structured Data Type Changes
The VideoObject structured data type is used by Google for displaying various kinds of rich results in Google Search, Google Discover, video search results and Google image search results.

Google previously only required the date that the video was first published.
What Google Changed
A structured data “type” is like a thing and a structured data “property” is an attribute of that thing (the structure data type).
Structured data then is comprised of a type and the properties of that type.
The change in the video structured data is that Google requires the time the video was publication.
This is accomplished by the use of the DateType structured data type.
Google’s documentation was updated with additional guidance in two sections.
