You want to sort the results descending for days but ascending for time?
Really strange, but that's your problem ;-)

<Information>
    <Date>02/04/02</Date> #yymmdd
    <Time>12:22:09</Time> #hhmmss
</Information>

<xsl:apply-templates select="Information">
    <xsl:sort select="Date" order="descending"/>
    <xsl:sort select="Time" order="ascending"/>
</xsl:apply-templates>
