Dates are not serializing correctly.

This is likely the same as #7.

Dates come out looking like this:

{
  "year": 2020,
  "month": 10,
  "day": 14,
  "hour": 9,
  "minute": 27,
  "second": 41,
  "fractionalSecond": 0,
  "timezone": -420,
  "date": "2020-10-14T16:27:41.000Z"
}

Instead they should just be the ISO string: "2020-10-14T16:27:41.000Z".
