time subtraction in xslt 1.0

sbutt · May 31st, 2013, 08:23 AM

Hi All,
I want to subtract '2 hours' from a given time in xslt 1.

E.g.

Code:

<xsl:variable name="time">
         <xsl:choose>
       <xsl:when test="ns0:DepartureTime !=''">
        <xsl:value-of select="ns0:DepartureTime"/>
       </xsl:when>
          <xsl:otherwise>
           <xsl:value-of select="'00:00:00'"/>
           </xsl:otherwise>
         </xsl:choose>
        </xsl:variable>

I want from this $time variable now subtract 2 hours and set it's value to an attribute.

Code:

<xsl:value-of select="$time"></xsl:value-of>

Could some please help?

XSLT 1.0 doesn't do dates or times, so basically you have to do string manipulation, or numeric manipulation.
