|Steps to Reproduce:||In the Graph API, the since and until parameters are applied to the post's creation time, not its updated time. Because we are looking for posts that have had comments added recently, restricting based on the post's creation time is useless for us. REST's stream.get allowed us to restrict based on the post's updated time.|
Note that the created_time of the google.com link in the first url is 2011-09-14T19:10:36, and its updated_time is 2011-09-14T19:11:18. 1316027400 corresponds to 19:10:00, and 1316027460 corresponds to 19:11:00. So when we pass in a since parameter of 19:11:00, which is in between the created and updated times, the post does not appear. A similar test can prove that the until parameter also applies to the created time, not the updated time. And if you look over the content of the feed, you can see that it is sorted by created time descending, not in order of updated time.
|Expected Behavior:||We need some way to filter and sort a page's feed by updated time, not created time.|
|Actual Behavior:||The Graph API's filter/sort mechanisms apply only to created time.|
