Today I tried out Windows Live Writer with my Wordpress.org blog. No issues at all with posting to the blog.
But, the date/time was out by 7 years - it posted with the date and time as November 30, 1999 at 2:00am, requiring a quick online edit to correct it.
I wrote about it here -

No other editor I use (ecto for windows) does this. Neither does it happen if I edit/post within WordPress.
It doesn't happen when I use Windows Live editor in posting to my WordPress.com blog, ie, the posting date/time is correct.
So it seems to be to be something in my WordPress.org date/time settings. But what? If everything else works ok, what do I need to double-check?
