OLEDate java implementation

Question

I need a good OLEDate java implementation, and this one does not seem to be working. Is there any known good opensource implementations (like in apache commons)? If not, where do I read about it, so that I write my own implementation?

Answer 1

This Old New Thing blog entry seems to be a decent treatise on the topic:

The OLE automation date format is a floating point value, counting days since midnight 30 December 1899. Hours and minutes are represented as fractional days.

If you have access to Visual Studio and the MFC COleDateTime source, you can reimplement that in Java.
