(was: I'm exciting to work on this issue for GSoC 2013. Would anyone like to 
mentor this project & give me further information about this project?)

> VXQuery utilizes Algebricks and Hyracks to build a XQuery processor that 
> execute on a cluster. Reviewing the list of query languages build upon the 
> same base, there is a common need for date/time/duration manipulation. XQuery 
> provides a great basis for other languages, like AsterixQL, wrt its 
> date/time/duration manipulation features. 
> Building a common library of this functionality for XQuery, AsterixQL, and 
> other languages on the Hyracks/Algebrix stack would allow for a simplified 
> code base.
> In addition to only having to implement these features in one place, the new 
> library could fill in the holes in VXQuery's implementation and provide 
> missing date/time/duration features for AsterixQL. 
> Key Features for Library:
>  - Written in Java 
>  - Optimized to work with out objects (use byte arrays)
>  - Standardized date/time/duration API
>  - Useful to other Hyracks applications 
> Review of tasks:
>  - Consolidate date/time/duration code into one library
>  - Update XQuery to use the library
>  - Validate all XQuery date/time/duration functions through the test harness
>  - Create a patch for AsterixQL for to utilize the new library
> Optional tasks:
>  - Additional non-XQuery date/time/duration features
