Availability_date ISO 8601

<g:availability_date>2016-11-25T13:00-0800</g:availability_date>

Hi, I love your plugin but have a serious problem – we make many of our products upon order, so availability is set to backorder. Google and FB needs a date in a specific format according to ISO 8601 (above)

I use your dynamic availability_date set +1 week but the format is not recognised by google as it is not showing daytime just the date.

Please is it possible to change the code for this? Or what is a solution?

Thank you.

Dana
