I guess, saving value of current-dateTime() at two different places within
an XSLT stylesheet, and computing the difference later might give us the
time spent by the enclosed XSLT instructions.
For your use case, I think to do this, extracting the component expressions
into their own variables might help to utilize the approach I've suggested.
