The GregorianCalendar used is left as it's public methods and some old code in Jena uses hands out Calendar. I've (slowly) been looking at java.time for other use in ARQ -- its all about details. java.time is ISO 8601 and not exactly XSD; e.g. duration/period is different and the support for xsd:g* isn't there exactly.
