HSSFListener - parse dates

[Pari Gandhi]

Hi I have written a program to convert an xls file to csv format & and Iam
having problems with parsing date values. 

I have uploaded my test xls file at
<http://rapidshare.de/files/16111340/x.xls.html>         


Expected Output:

ABC,10/10/2005,12/10/2007,10/10/2005,123.12451,1234.125235,BDS
XXX,01/01/2012,24/11/1984,21/02/2005,214.234,124.234,SSS

Actual Output:

ABC,38635.0,12/10/2007,10/10/2005,02/05/1900,1234.125235,BDS
XXX,40909.0,24/11/1984,21/02/2005,01/08/1900,124.234,SSS

Can someone help me to solve this problem?

Thanks
