Can an XSLT insert the current date?

XSLT 2

Date functions are available natively, such as:

<xsl:value-of  select="current-dateTime()"/>

There is also current-date() and current-time().

XSLT 1

Use the EXSLT date and times extension package.

1. Download the date and times package from GitHub.
2. Extract date.xsl to the location of your XSL files.
3. Set the stylesheet header.
4. Import date.xsl.

For example:

<xsl:stylesheet version="1.0" 
    xmlns:date="http://exslt.org/dates-and-times" 
    extension-element-prefixes="date"
    ...>

    <xsl:import href="https://stackoverflow.com/questions/1575111/date.xsl" />

    <xsl:template match="//root">
       <xsl:value-of select="date:date-time()"/>
    </xsl:template>
</xsl:stylesheet>
