That for-each select="." does not achieve anything.

The "statistics" element does not have preceding sibling elements of the 
same name, I think you want
         <xsl:variable name="end"
            select="../preceding-sibling::entry[1]/statistics/time"/>

Doing
         <xsl:variable name="start" select="time"/>
is shorter, easier and more efficient.
