when parsing items where the pudate/ created is december (dec) exception will occur.
the template match in the all.xsl file for "xsl:template mode="rfc2822-w3cdtf" match="*"" will not find any date that contains dec because the test condition is testing for "DEV" instead of "DEC"
can you confirm this solution ?
replace "dev" with "dec" in test contion ->
<xsl:when test="$m-temp='dec'">
<xsl:value-of select="'12'"/><br/>
</xsl:when>
