It wouldn't be as useful as you think. Let's say you use an extension
function that does this, as has been suggested:

<xsl:variable name="startTime" select="xx:current-dateTime()"/>
... do some processing ...
<xsl:variable name="endTime" select="xx:current-dateTime()"/>
<xsl:message select="$endTime - $startTime"/>

The final result will be a negative duration, because Saxon will evaluate
$endTime before it evaluates $startTime.
