There seems to be a issue with the time parsing when creating posts.
If I set the Postie Time Correction: option to 0 times added to email using the date: August 1, 2013 14:00:00 format is posting at the correct time.
But then posts that are sent without the date: parameter is to hours in the past.
Setting the Time Correction to 2 will lead to posts with no specified time having the post time as the same as when it was collected. While posts that has the date: sett vil be posted 4 hours later than the time specified in the e-mail
Guess there is some sort of timezone hick up here somewhere.
