Timezones get lost in date/time rendering #37

Closed namedgraph closed 3 years ago

After 3 edits, dct:created value is shown as being later than dct:modified:

However in the RDF data the values correct, only the timezones are different (GMT+2 and GMT (Z)):

It looks like we'll need to use adjust-dateTime-to-timezone() to normalize all xsd:dateTime values to the same timezone (which we need to supply via a param such as $ac:timezone).
