order managment javascript code change

Not sure if this is just our order managment pages or not. Today is the 1st and when you go into Control Panel/Manage Orders/Purchase orders ...... you view 'Order Retrieval' with a bunch of sections. The top one 'by Date' has Today, Yesterday, 2 days Ago, and 3 days Ago option buttons. On the first few days of each month your javascript may not provide the proper date if you select anything other then Today.   I have found some code online that may help and I will provide what I have.

Will, can you give some feedback on if you also have this same issue and if this will work?

If anyone finds issues with this please provide some feedback for everyone that uses this.

-page with javascript: shop/online/3_order.asp
-javascript function: AddDay

<code>
function AddDay(xdays){
     var now = new Date()
     var day = now.getDate() - xdays
     var month = now.getMonth() + 1
     var year = now.getYear()
     var dateValue = "" + month + "/" + day + "/" + year
     
     //Start of new code
     if (day < 1){
           // original source code from http://developer.irt.org/script/1127.htm
           var today = new Date();     
           var MonthDays = new Array(31,28,31,30,31,30,31,31,30,31,30,31);
          
           theYear = today.getYear();
           if (theYear < 1000) theYear +=1900;
          
           StartOfThisYear = new Date(theYear,0,1);
           EndOfThisYear = new Date(theYear,11,31);
          
           StartOfLastYear = new Date(theYear-1,0,1);
           EndOfLastYear = new Date(theYear-1,11,31);
          
           if (today.getMonth()==0) {
           StartOfLastMonth = new Date(theYear-1,11,1);
           EndOfLastMonth = new Date(theYear-1,11,MonthDays[11]);
           }
           else {
           StartOfLastMonth = new Date(theYear,today.getMonth()-1,1);
           LastMonth = today.getMonth()-1;
           DaysInLastMonth = MonthDays[LastMonth];
           if (LastMonth == 1) {
                 // February
                 if (theYear%400==0 || (theYear%4 == 0 && theYear%100!=0) )
                      DaysInLastMonth +=1;
           }
           EndOfLastMonth = new Date(theYear,today.getMonth()-1,DaysInLastMonth);
           }
           //Recalculating date
           now = EndOfLastMonth
           day = now.getDate() - xdays + 1
           month = now.getMonth() + 1
           year = now.getYear()
           dateValue = "" + month + "/" + day + "/" + year
     }
     //End of new code
     
return dateValue;

Will,
Thanks for the response. I looked at the support page and looks like you only provide support for 60 days. What url are you referring to when you say a support ticket?

This was just one issue that was fixed. I imagine that others have been fixed as well. Can we get those as well or do we have to pay for them? Just wondering what the process is. Plus, could be a major pain since we may have coded for a lot of these already. Do you also provide what code has changed for us developers that do add-ons to your purchased code?

Thanks
