No, I was implying adding a unique number, not necessarily a timestamp. 
One way (and imho the preferred way) is doing this by retrieving the id 
of a newly created node:

<xsl:function name="f:my-id">
   <xsl:variable name="new-node">
         <node />
    </xsl:variable>
    <xsl:sequence select="generate-id($new-node)" />
</xsl:function>

Now, calling f:my-id() will always return a unique id within the 
session. If you also need a unique id globally, add a timestamp or use 
my GUID techniques.
