-----------------------------------------

Hi Patrick,
I would like to work on this issue. Seems like the date conversion is thrown 
off by the time-zone adjustments and the fact that the interchange type is days 
instead of millis. I am preparing a pull-request which will also include test 
cases to cover more date conversion scenarios.



> DateUtils can not handle date before 1970/01/01 correctly
