The timestamp is used to uniquely identify batch files and DOI values when a DOI has been updated one or more times. timestamp is an integer representation of date and time that serves as a version number for the record that is being deposited. We don't mandate a specific timestamp format, but YYYYMMDDHHMMSSmmm is recommended. When you update the record for a DOI, our system compares the timestamp in your update to the timestamp of the previous submission of the DOI. If the update has a time stamp value that is greater than the timestamp used for the previous update, the new data will replace the old data. If the new timestamp value is less than the old timestamp value, the update will be rejected. </xsd:documentation>
