Arithmetic Operators on Durations, Dates and Times with jena

The development version of ARQ now includes support for operations 
involving durations for operators "+" and "-", following the operations 
in "XQuery/Xpath functions and operations" (F&O).

Some of this uses the Java runtime support for XML datatypes, which is 
slightly more permissive than the F&O specification (e.g. you can add a 
any xsd:duration to xsd:time, not just xsd:dayTimeDuration - Java 
forgets about the meaningless parts).

Supported:
datetime, date, time   +   duration
     (also duration + datetime, date or time)
datetime, date, time   -   duration
dayTimeDuration * number - > dayTimeDuration

Thank you for your replay.

I'll test it.
