    A subclass of JSONEncoder that can convert datetime and date objects to an
    RFC3339-compliant string format. The resulting format is always:
       `YYYY-MM-DDTHH:MM:SS.SSSSSSZ`

    A falcon media handler that can encode and—if keyed with "date", "datetime",
    or "timestamp"—decode between RFC3339 datetime strings and Python datetime
    objects.
    - The format string used for datetimes is '%Y-%m-%dT%H:%M:%S.%fZ'
    - The format string for dates is '%Y-%m-%d'
    - The encoder always outputs the full RFC3339 datetime string.
    - The decoder always assumes UTC, and expects a string in one of the above
      formats, or an integer or float POSIX timestamp.
