Flickr for iPhone: Timestamp problem?

I am not sure when this kind of problem appeared for the first time. Not exactly a big problem, but something that does not work well. I’m now using Flickr for iPhone Version 1.4.2 on iPhone 4 (Software Version: 4.3.5), and so far the primary feature — I consider photo upload feature as primary feature here — works well. At least, it helps me a lot to upload photos taken using my iPhone directly to Flickr.
I know, there are some other methods that I use like transferring photos using Image Capture or iPhoto to my laptop and upload them using Flickr Uploadr. I almost never use Email-to-Flickr feature.
Okey, back to the problem.
When I go to “Activity” tab, I see that there are some activities on uploaded photos (new comments, favorited, and added to gallery by other users). But, there is a single activity that should not be there. The latest activity should be on the top — and I think this is what Flickr (for iPhone) exactly want to have. You can see “655 days ago” there. It is a valid activity, and I’ve checked from the web browser.
So, I tweeted about this small issue. I’m not sure how many other Flickr users out there who have the same issue. Karen Yeo (Hi Karen!) came with an idea to re-authorize the application. I did it, but I think I need to be more patient to have it fixed. Is it an issue on the application? Not sure.
I’ll wait.

I’m still curious. I’m now with iOS 5 now. So, I just tried a different approach to see how whether it solved the problem or not.
I logged in using my other account and liked my own photo to see whether the “old activity” disappeared or not — considering that they’re displayed by date/time. It didn’t.
