From the time you start typing or just before you hit "Publish Post"

Do you Change your Time & Date to match the time you started typing or the time you finished?

I find that my articles get long sometimes and I don't know what sense it would make to save a draft and pretend you finsihed the article back before you had even saved a first draft.

I choose to change the time to when I finish the article.

The time currently says 2:25 PM Sep 4 2005

Since it took two minutes to write the article I will change it to 2:27
