Of course, but first one needs to know how other times are represented. Is
01:30 represented as "01:30", as "0130", as "90", or in some other way? And
is 00:05 represented as "5" or as "05"?

Sure. In XSLT 2.0 do

<xsl:for-each select="1 to 7">
  <TD>
    <xsl:if test="substring($in, ., 1) = 'Y'">
      <xsl:attribute name="color">green</xsl:attribute>
    </xsl:if>
    <xsl:text>S</xsl:text>
  </TD>
</xsl:if>

In 1.0 the simplest solution is probably simply to unfold the loop, i.e.
repeat the content of the above for-each loop seven times changing the
second argument of substring() each time.
