Version: 2
Status: implemented
User Page: index.html
XML Definition: date.add.xml
Function Package: date.add.zip

Function Syntax

Template Syntax

<xsl:call-template name="date:add">
   <xsl:with-param name="date-time" select="string" />

The date:add function returns the date/time resulting from adding a duration to a date/time.

The first argument must be right-truncated date/time strings in one of the formats defined in [XML Schema Part 2: Datatypes]. The permitted formats are as follows:

The second argument is a string in the format defined for xs:duration in [3.2.6 duration] of [XML Schema Part 2: Datatypes].

The return value is a right-truncated date/time strings in one of the formats defined in [XML Schema Part 2: Datatypes] and listed above. This value is calculated using the algorithm described in [Appendix E Adding durations to dateTimes] of [XML Schema Part 2: Datatypes].

An implementation of this extension function in the EXSLT date namespace must conform to the behaviour described in this document.
