如何在XSLT中编写当前日期+1小时的代码

<xsl:variable name="currentDateTime" select="current-dateTime()"/>

<xsl:variable name="adjustedDateTime" select="adjust-dateTime-to-timezone($currentDateTime, 'PT1H')"/>

<xsl:value-of select="$adjustedDateTime"/>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes"/>
  
  <xsl:template match="/">
    <xsl:variable name="currentDateTime" select="current-dateTime()"/>
    <xsl:variable name="adjustedDateTime" select="adjust-dateTime-to-timezone($currentDateTime, 'PT1H')"/>
    
    <result>
      <xsl:value-of select="$adjustedDateTime"/>
    </result>
  </xsl:template>
</xsl:stylesheet>
