Dan,
If you open the forum where Chris' updates are, you will find four posts.
Starting with the bottom post and moving upwards, they are dated properly. The top post is dated in March correctly. Each post that is made is dated or time stamped, and these cannot be changed without quite a bit of time working in the Control Panel by an admin.
Each of the first three posts from the bottom also match up with the date it was posted. If a post is "re-posted", which I believe the top one was, the date of the post will stay the same, but the date it was posted will change to the day it was actually posted.
So, there are two very small issues with the posts. One is the the top post should be moved down (not worth the effort), and that one post (the top one) appears to be posted at the wrong date. While this can cause confusion, it is what it is, and I doubt it will be changed.
This does not address the fact that the posts are not coming monthly, a result of biting off more than one can chew. Quarterly, which is what it seems to be currently, would have made more sense.
