Emits a document timestamp value object (/Type /DocTimeStamp, /SubFilter /ETSI.RFC3161) whose /Contents is a bare RFC 3161 timestamp token. It is added in an incremental update to reach PAdES B-LTA. It shares the /ByteRange and /Contents placeholders with the signature value object so the host’s signing pass locates them the same way for either object type.
