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.
The same as with any other WordPress plugin:
- Upload
posts-by-gmt.php to the /wp-content/plugins/ directory.
- Activate the plugin through the 'Plugins' menu in Wordpress.
- That's it. There are no configuration options.
