Description Jesper Moller CLA 2011-03-25 21:00:53 EDT 
xs:dayTimeDuration relies on javax.xml.datatype.Duration.getTimeInMillis() which takes a date to do the year and monts stuff correctly.

For our usecase, this is bad, since it also takes daylight savings time into account. Suddenly, 2 days and is not 2 days if you are two days away from a DST switch, which we happen to be in Denmark right now.

The fix is to use the fields as they are, and not meddle with javax.xml.datatype.Duration for math.
