[NancyFx] date field mapped to ZonedDateTime

[craffael]

Description

If a definition in a swagger spec contains a field with format: date, the corresponding c# field is of type NodaTime.ZonedDateTime. This is wrong as a date field itself does not carry any time/time-zone information. One particular problem with this is that the corresponding field is serialized wrongly as a RFC3339 full-time instead of a full-date.

There is no related issue that I'm aware of.

Suggest a fix/enhancement

Use NodaTime.LocalDate instead and add a Nancy.Json.JavaScriptPrimitiveConverter that uses the RFC3339 full-date pattern.
