I've installed 5.2.13 on our plushcatalog store, but I found when checking some emails that the order date in the email for a test order shows as 1408134298 - not written as a calendar date. I expected it to be 08/15/2014. I used {$DATA.order_date} in the email template.   I haven't checked the customer emails in a long time, so this may not have anything to do with this upgrade. Your help is appreciated.
