Magento email template format date of invoice

I'm trying to apply the german format of a date to a Magento email. I can get the invoice date with

{{var invoice.created_at}}

but that gives me "2010-05-21 15:46:24". I would like to have 21.05.2010 and PHP doesn't work in the templates.

I'm total开发者_运维技巧ly new to Magento so please be patient :-P

I think you will have to override the method that sends the email to pass the date as a variable to the template (using the fifth argument of the sendTransactional() method).

You could also call the order.getCreatedAtStoreDate()-function:

Order date: {{var order.getCreatedAtStoreDate()}}
