Thanks Christian Meantime (quite short one) I found the answer

let $tsta := xs:dateTime("2011-01-15T12:00:00Z") let $tsto := xs:dateTime("2011-01-17T14:40:00Z") let $dur := $tsto - $tsta return $dur div 2

And as usual, you were faster in reaction, then I.

Have a nice Sunday.

Hi Jan,

all XQuery functions which use the "op" prefix are part of other XQuery expressions and cannot be explicitly called. In your example, you can use the "div" operator to get the expected result. Example:

xs:dayTimeDuration("P1DT2H30M10.5S") div 1.5

Hope this helps, Christian

Hi I am trying to use function op:divide-dayTimeDuration as declared at http://www.w3.org/TR/xquery-operators/#func-divide-dayTimeDuration BaseX tells me either unknown namespace op, or unknown function. Is this supported by BaseX, or I shall find my own implementation written

XQuery? Jan
