A question about finding store content by date in the mediafire downloads

Yeah, the title. Hey, so I was wondering if there is a way to find the date of a specific 'product'. For example, http://store.thesims3.com/productDetail.html?productId=OFB-SIM3:19067 I can't seem to find in which month, year, whatever, that is located in. Could I open the source of something to find out what date it was made on or to TS3 store? So I can find them in the store updates downloads. Like if I knew it was December 10th, 2010, I would look in December. Can't seem to find it.

Not sure if there is a way, would have seemed likely someone would have found out if there was tho.
