Re: Bug in IBM Date Routies %month

Hi Praveen,

Actually, that's not a bug, it's a problem with intermediate values.  
When you add 1 month to 2006-01-31, what do you get?  2006-02-31 is not 
a valid date; instead you get 2006-02-28 (see the manual).  When you 
then add 1 month to that, you get 2006-03-28.  Date arithmetic is tricky...
