No, current-dateTime() is explicitly defined to give constant results
throughout an evaluation. That's because there isn't any defined order of
execution, so "later" has no meaning.

There is a function saxon:timestamp() designed to get around this. But at this
level of granularity the results are going to be meaninless.
