Oledate Java implementation

I need a good oledate Java implementation, and this one doesn't seem to work Are there any known good open source implementations (such as Apache Commons)? If not, where do I read it so that I can write my own implementation?

Solution

This old new thing blog entry seems to be a decent paper on this topic:

OLE automation date format is a floating point value that calculates the number of days since midnight on December 30, 1899 Hours and minutes are expressed as decimal days

If you can access visual studio and MFC coledatetime source, you can re implement it in Java
