[Feature Request] Support auto timestamps?

[raphaelsoul]

Any idea about timestamps support?

what we need might be auto add timestamp when posting a resource. And timestamps fields and format could be customized. 🍻

As provided on README.md

module.exports = (req, res, next) => {
  if (req.method === 'POST') {
    req.body.createdAt = Date.now();
  }
  next();
};
