Non-publication date used within a bibliographic reference, for example, an access-date or a time-stamp.
A <date-in-citation> element should not be used to record the publication date (use <date>). This element can be used to record dates such as access dates, copyright dates, patent application dates, or time stamps indicating the exact time the work was published for a continuously or frequently updated source.
