fn:current-time() as xs:time
  Returns xs:time(fn:current-dateTime()). This is an
  xs:time (with timezone) that is current at some time
  during the evaluation of a query or transformation in which
  fn:current-time() is executed. This function is
  *stable*. The precise instant during the query or transformation
  represented by the value of fn:current-time() is
  *implementation dependent*.
fn:current-time() returns an xs:time
  corresponding to the current date and time.  For example, an
  invocation of fn:current-time() might return
  23:17:00.000-05:00.
fn:current-time() => 18:24:06-07:00
