I figured it out. I needed to restructure the variable definition of
page-time-stamp.


				<xsl:variable name="page-time-stamp">
					<xsl:choose>
						<xsl:when test="@time-stamp">
							<xsl:value-of select="@time-stamp"/>
						</xsl:when>
						<xsl:otherwise>
							<xsl:value-of select="$time-stamp"/>
						</xsl:otherwise>
					</xsl:choose>
				</xsl:variable>
