[Bug 55649] New: ATP - WORKDAY Function returns incorrect date

https://issues.apache.org/bugzilla/show_bug.cgi?id=55649

            Bug ID: 55649
           Summary: ATP - WORKDAY Function returns incorrect date
           Product: POI
           Version: unspecified
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: POI Overall
          Assignee: dev@poi.apache.org

Patch with Unit Tests and Fix

When spanning a weekend, or the start date is a weekend, the WORKDAY function
returns an incorrect result. There are probably a lot of other circumstances
where it could have returned an incorrect result.

As an example

WORKDAY(DATE(2013,09,30),-1)

should return 2013/09/27 

but actually returns 2013/09/24

I have attached a patch which includes some new Unit Tests to reproduce the
issue, and also a fix for the function to make the tests pass.
