RSS duplicate items

In feedreader, my getsatisfaction RSS feeds keep showing duplicates.
This is because each article ends with

"This reply was posted about 9 hours ago"

So if I check the feed the follwing day, I would get for the same article

"This reply was posted 1 day ago"

Although the text in the feed item has not changed, only this part changes and the rss reader detects a change, so I keep getting older items re-displayed as new unread items.

Could add an option to remove the date indication in the feed items? I do not understand the purpose of this indication, as rss readers are able to get the time directly as reported by the feed, no need to embed this information in the body of each feed item. It just adds useless noise.
