iso-8601-date ISO-8601 Formatted Date

A machine-processable, ISO 8601 formatted date value (“YYYY-MM-DDThh:mm:ss”) for a JATS date-specific element, whether the content of the date be specified as text, an ISO date, a partial date, or as any other date format. If the date given in the content of the element is in a non-Gregorian calendar, this attribute can hold the Gregorian calendar equivalent of that date.


The ISO date format (“YYYY-MM-DDThh:mm:ss”) may be used, for example, to add processable numeric month value and day values to a date element given in the text form: “January 24, 2021”:
  <date-in-citation specific-use="access-date" 
      iso-8601-date="2021-01-24">January 24, 2021</date-in-citation>
The hours, minutes, and seconds of the @iso-8601-date values may be used to include a timestamp for a date, for example, when a publication date has both an embargo date and an embargo time.
