Answer 1

XPath 2.0 has a function for that:

XSLT 2.0

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="/chatTranscript">
    <chat>
        <time>
            <xsl:value-of select="adjust-dateTime-to-timezone(@startAt, ())"/>
        </time>
    </chat>
</xsl:template>

</xsl:stylesheet>
