Whenever I need to send dates across the wire with a JSON API, I sort of miss XML a little bit. It's a lot easier, and there are existing patterns and tools to help there. JSON really only supports three data types - boolean, numeric, and string. Any other type needs to be fiddled with some ad-hoc system for communicating the schema or just expecting created_at to be a date. XML, on the other hand, had the ability to do something using attributes in the element or a DTD / XSL. Occasionally I do miss that ability to communicate data schema alongside the data. But only occasionally.
