Hi Chris,

you did import the exslt date stylesheet, didn't you?
(I don't see it in your fragment):
<xsl:import href="date.xsl" />

If you didn't, your stylesheet will know nothing about the named extension 
templates (in other words, you're calling templates that don't exist)

But I suppose you did import it... Then take a look at your template calls:

  <xsl:call-template name="date:hour-in-day"/>

You are calling the template with no parameters! How can the template
know what date/time you want to extract the hours of?

You will need something like:

  <xsl:call-template name="date:hour-in-day">
    <xsl:with-param name="date-time" select="$date-str"/>

If you want the current system time, you will need to call the
appropriate function "date:date-time()".
