Neat!

If you are willing to rely on EXSLT support in the XSLT processor, you 
  could do like I did in our XSL-FO customization layer. It works with 
Saxon and xsltproc. Don't know about Xalan.

Here is what I did:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                 xmlns:fo="http://www.w3.org/1999/XSL/Format"
                 xmlns:xlink='http://www.w3.org/1999/xlink'
                 xmlns:date="http://exslt.org/dates-and-times"
                 exclude-result-prefixes="xlink"
                 version="1.0">

<!-- Note the xmlns:date="..." above -->

<!-- SNIP (Imports and other customizations) -->

<!--
      Template formatted for readability.
      May produce extra blanks.
      Add number formatting to ensure two digits in
      time fields.
  -->
   <xsl:template match="pubdate[@role='now']" mode="titlepage.mode">
     <xsl:variable name="now" select="date:date-time()"/>
     <fo:block>
       <xsl:text>Generated at </xsl:text>
       <xsl:value-of select="date:day-in-month($now)"/>
       <xsl:text> </xsl:text>
       <xsl:value-of select="date:month-name($now)"/>
       <xsl:text> </xsl:text>
       <xsl:value-of select="date:year($now)"/>
       <xsl:text> </xsl:text>
       <xsl:value-of select="date:hour-in-day($now)"/>
       <xsl:text>:</xsl:text>
       <xsl:value-of select="date:minute-in-hour($now)"/>
       <xsl:text>:</xsl:text>
       <xsl:value-of select="date:second-in-minute($now)"/>
     </fo:block>
   </xsl:template>

<!-- ETC -->

</xsl:stylesheet>



Document:

<!DOCTYPE book PUBLIC "..." "...">

<book lang="en">
   <bookinfo>
     <title>Blah blah/title>
     <pubdate role="now"/>
     <!-- ETC -->
   </bookinfo>

<!-- ETC -->
</book>
