If you are using Blogger ...

For dcblogs live feed users only ....

If you are using Blogger, please make this change:

To ensure that your blog appears at or near the top of the feed when you publish, go to Blogger's Settings and change the Time Zone to [UTC+00:00] Greenwich Meantime.

Typepad, Wordpress, etc., don't have to do a thing.

I've reset the time to GMT for this blog and when I published it appeared on top of the feed. I've heard from a couple of people who have had trouble making this change. But Blogger does allow the time zone to be changed ....
