Previous to my last update to 1.6.1 the date format when creating a post from a form was yyyy-mm-dd. It appears that it has now switched to mm/dd/yyyy or dd/mm/yyyy. This is creating problems because any new post that are being created have the wrong date because of the translation between the date formats.
I am having problems in verifying this because today is 11/11/2011. i.e. this date is the same for mm/dd/yyyy (US format) and dd/mm/yyyy (Australian format).
Could you please check it out.
