…what I forgot to say: you can simply use the plus operator to add dates and durations:
xs:date("2004-10-30Z") + xs:dayTimeDuration("P2DT2H30M0S") _______________________________________

Hi Jean-Marc,
back from my vacation.. I’ll try to give feedback to your (and all other) pending mails as soon as possible!
I am trying to add dates and duration through BaseX, in conformance with http://www.w3.org/TR/xpath-functions-30/#func-add-dayTimeDuration-to-date.
However, BaseX interpreter does not recognize the function add-dayTimeDuration-to-date, nor op:add-dayTimeDuration-to-date.
Functions using the op prefix are not available directly to users. The spec says that “Functions defined with the op prefix are described here to underpin the definitions of the operators in [XML Path Language (XPath) 3.0], [XQuery 3.0: An XML Query Language] and [XSL Transformations (XSLT) Version 3.0]. These functions are not available directly to users, and there is no requirement that implementations should actually provide these functions. For this reason, no namespace is associated with the op prefix.” [1].
Hope this helps! Christian

Did I misunderstood something ?
Thanx for your answer,
Cheers,
