Problem with valid date time stamps

Darlene - when I look at your feed (via the email you sent), I can see that there are no dates on the individual items, but these are needed by twitterfeed to determine if an item in the feed is new and should be posted to twitter.
Looking a little closer, you're using feedburner with wordpress, and I think the issue is that you're using a RSS 0.92 feed - which doesn't provide dates - while Wordpress also provides a RSS 2.0 and Atom feed.
Perhaps you could change the feed URL in your feedburner settings for the account (under "edit feed details"), and if the entry in the "Original feed" textbox ends with "feed=rss", change that to "feed=rss2". This should then pick up your RSS 2.0 feed which will/should contain date stamps on each feed item.

Hope this helps - let me know..
Mario.

You may want to check with feedburner support, but I wouldn't have thought changing the "original feed" URL would cause a problem. In essence you're telling feedburner to pick up a different feed, but in your case that's what you actually want to do.

someonespecial: the reason for this is that your links on the individual items are all the same. twitterfeed checks these to avoid posting duplicate entries, on the assumption that each item in a feed contains a unique link to itself.
In a case like yours, the easiest way to get this to work is to uncheck the box that says "include item link" in the twitterfeed settings for this feed - the link is not really very useful in this case, as it's always the same, and this will also give you more characters to play with. If you don't include the link when posting, then twitterfeed won't check it and will post any items that are new according to the publish date.

I believe it's because the dates are not in a valid format, see also http://feedvalidator.org/check.cgi?ur...

If you look at the source of the feed, you can see that the individual items don't contain a date entry. twitterfeed needs this to know if an item is new and should be posted. I haven't really used Yahoo Pipes myself so am not sure how you'd make sure there is a pubDate for each entry, but perhaps someone at their support end could help.

I can't answer this for you - I would try and see if there are any terms regarding their RSS feed on the site providing the feed. Different companies have different terms of use for their RSS content.
