It just occurred to me that there is no last post date on threads. However, if I post something to and old thread on the last page of the results, that thread shows up on the first page of the results again. This implies that the forums are sorted by the date of the last post.
Can we get the date as a hidden value on the forum posts please? I have systems in place to show me all posts for a particular time period, but I need the last post date and time to avoid scraping the entire forum every five hours.
