This question isn't about how to change the Magento data/time format.
I use a third-party shipping platform that stores delivery date as part of the order and the delivery date is order specific. It is held in the DB against the order.
Their extension exposes that data as a variable - {{var deliveryDate}} for inclusion in transactional emails and that bit works ok.
The problem I'm having is they store the date as UTC YYYY/MM/DD in the database and it's confusing for UK customers to read dates in that order.
My question is does anyone know if there is there a way in PHTML that enables me to change the display of that variable into something more UK friendly?
I'm not trying to change the display date in the frontend, I know how to do that, this is changing the format of a specific variable from a 3rd party extension. Would appreciate that help everyone.
