Some people were wondering how I could have posted everything I ate in a day by 4pm. At first I thought it was just that I had my timezone set improperly when I setup the new blog, so I fixed that. Then I noticed that today's entry did the same thing. Huh?
I figured it out. I actually started the post at 4:42pm to go ahead and list what I had eaten thus far and just left it sitting there to finish tonight. Finished it and posted it. Blogger defaults to use the time you STARTED the post, not the time you finished it. There is a "Post Options" link under the edit window of new posts, and you can change your posting time that way to reflect current time if you like.
Very odd that you can't set that to do publish-time instead of "started typing" time.
