New Blogger Datestamp bug
The new blogger system allows you to type out a post and "Save As Draft" before publishing. This feature is very helpful as it allows you to work on upcoming, future posts, reread your posts, preview posts and fine tune posts before you set them live for the world to see. Unfortunately, if you publish one of your drafts days later, the article will retain the date stamp of the first time that you saved the post.
Just take this post for example! I started writing this post on April 6th, 2007 and saved a draft. I did not publish the post until April 7th, 2007, but it still retains a date stamp of April 6th! The new blogger system definitely has some bugs and nuances that the Blogger development team needs to work out.
