 * When testing at a couple places (yandex/structured-data.org) I get a date error:
 * “WARNING: the “Mar 9, 2016″ value in the datePublished field is not a valid date.
   Dates should be in the ISO 8601 format”
 * ?

 * I am not sure where this came from, but I’ve made a check now and modified a 
   couple of functions for getting the datePublished and dateModified markups to
   make sure it always output in ISO 8601 format.
 * I will add this to the next update, it will be ready soon.
