I was a little confused as the time of a post says GMT after it and at the bottom of the list it says all times are GMT +9 - i.e. Japan Standard Time (JST). I assume then that all posts are in JST - in which case I would suggest removing the GMT from the post time...
Just a thought... I've worked it out now but no big deal
For the record this post is around 17:33 JST or 08:33 GMT
