The date of the message is correct for my personal message. The example mbox 
file actually also shows the correct date (as posted in the original report), 
because the article at issue was dated Fri, 13 Oct 2000 10:15:42 +0900 in the 
mbox file, and I am on GMT-7, therefore 12 Oct 2000 was the correct date for me.
