I'm happy with that and I agree it's very useful. It wasn't in the list
we decided on so I haven't included it. It should return the same
dateTime throughout the query execution. c.f. fn:current-dateTime
("This function is ·stable·")
ARQ already has afn:now() - TZ is locale but of course you can run your
locale in Z.
In the useful camp might be VERSION()->string (unless security concerns?)
