Well, you haven't shown us your code, so you can't expect us to debug it for
you.

But I would think the following should work:

<xsl:variable name="base" select="*[not(self::C)][1]/@start"
<xsl:for-each select="*[not(self::C)]">
 <xsl:copy>
 <xsl:variable name="start" select="$base
         + sum(preceding-sibling::*[not(self::C)]/@end)
         - sum(preceding-sibling::*[not(self::C)]/@start)
         + count(preceding-sibling::*[not(self::C)])"/>
 <xsl:attribute name="start">
   <xsl:value-of select="$start"/>
 </xsl:attribute>
 <xsl:attribute name="end">
   <xsl:value-of select="$start + (@end - @start)"/>
 </xsl:attribute>
 </xsl:copy>
</xsl:for-each>

Not tested.
