Calling "impure" functions in XSLT is always problematic; the more

Michael - I have noticed that calling the function current-dateTime()
multiple-times within one XSLT invocation seems to always give the
same result even if a significant amount of time has elapsed - is this
for the same reason? If so there anyway to fool the optimiser? (In
this example I was usingSaxon 9.1.0.8).

I don't think it is any optimization causing that, the function
http://www.w3.org/TR/xpath-functions/#func-current-dateTime
is supposed to return "the current dateTime ... from the dynamic context". And the XSLT 2.0 spec clearly says:
"The current date and time represents an implementation-dependent point in time during processing of the transformation; it does not change during the course of the transformation."
