public annotation Document.CreationTimestampMillis
Marks a member field of a document as the document's creation timestamp.
The creation timestamp is used for document expiry (see TtlMillis) and as one of the sort options for queries.
This field is not required. If not present or not set, the document will be assigned the current timestamp as its creation timestamp.
If present, the field must be of type long or Long.
See the class description of Document for other requirements (i.e. if present it must be visible, or have a visible getter and setter, or be exposed through a visible constructor).
