This is a simple plugin that enables users to modify the order in which posts are displayed on all pages(or in selected categories) of the blog. This is very useful when 
you have a blog in which you want to display posts in the order they were posted, from the first post being the oldest one, to the last post which 
is the most recent one, or the other way around. The options provided with the plugin at this moment allow users to order the displayed posts by post date, post title, 
post author, last time modified and post slug, either ascending or descending.
These post display options can be set by accessing the “Manage->Custom Post Order” link, for wp2.6, and “Tools->Custom Post Order” link, for wp2.7.

Most people don’t need this plugin. Most wouldn’t notice a difference if they had it. All it does is change the default sort order of a WP_Query from posts.post_date to posts.post_date_gmt — that is, sort on the GMT timestamp of a post rather than the local time zone.
Who needs this? People who switch time zones frequently. People running a network installation of WordPress where they want to be able to aggregate posts from all their network blogs easily, and in the right order. I don’t know. I wrote it for FreeThoughtBlogs.com, so their “most recent posts” sidebar would stop showing only posts from a few blogs in early time zones. If it works for you, great.
I have every hope that this plugin will be made obsolete by the default sort order being changed in the WordPress core. I can think of no good reason why comments are sorted by GMT but posts by local time.
For all I know, this plugin works with older versions than 3.0. I’ve only tested it with 3.2.1.
