If you have a date column "theDate", you can select the values theDate and  theDate_UDT_Value. The later one contains a formated. localized date.

If you need more, you will need to play with theDate. Perhaps this code fragment helps you:

<xsl:template name="OutputValue">
    <xsl:param name="Value"/>
    <xsl:param name="FieldType"/>
    <xsl:if test="$Value">
        <!--DateTime looks like "2005-12-31T23:59:55.0000000+01:00" -->
        <xsl:variable name="Year" select="substring($Value, 1, 4) "/> 
        <xsl:variable name="Month" select="substring($Value, 6, 2) "/> 
        <xsl:variable name="Day" select="substring($Value, 9, 2) "/>
        <xsl:variable name="Time" select="substring($Value, 12, 8) "/>
        <xsl:choose>
            <xsl:when test="$FieldType='Date' or $FieldType='ChangedAt' or $FieldType='CreatedAt'">
                <xsl:value-of select ="$Month"/>/<xsl:value-of select ="$Day"/>/<xsl:value-of select ="$Year"/>
            </xsl:when> 
            <xsl:when test="$FieldType='DateTime'">
                <xsl:value-of select ="$Month"/>/<xsl:value-of select ="$Day"/>/<xsl:value-of select ="$Year"/><xsl:text> </xsl:text> <xsl:value-of select="$Time"/>    
            </xsl:when> 
            <xsl:when test="$FieldType='Time'">    
                <xsl:value-of select="$Time"/>
            </xsl:when> 
            <xsl:otherwise>
                <xsl:value-of select="$Value" disable-output-escaping="yes"/>
            </xsl:otherwise> 
        </xsl:choose>
    </xsl:if>
</xsl:template>
