[typescript-angular2] Handle date type correctly

[taxpon]

Description

• As mentioned in Typescript: Dates Are Not Deserialized #2776, typescript clients do not handle date type correctly.
• I think api clients should convert ISO8601 string into Date object when receiving request, convert Date object into ISO8601 string when sending request.

Swagger-codegen version

Suggest a Fix

I am thinking updating of api.mustache of typescript-angular2. If it's ok, I'll create PR.

@taxpon yes, the typescript-angular2 client still needs some work and proper date/datetime handling is one of them. It would be great if you can contribute the enhancement with a PR.

I would suggest that the desiralization of date are not handled by swagger codegen, I am sure that Angular 2 has a extensibility point for deserializing similar to Angular 1 see #2776

@moanrose thanks for the suggestion. For other langauges (e.g. C#, Java, Ruby, Python, etc), the auto-generated SDK handles the deserialization of string back into datetime object in the language automatically so doing the same in Angular 1or 2 API client will make the developer experience more consistent.

If it's more common for Angular 1 or 2 developers to handle the deserialization in their own program, then one workaround I can think of is to document the datetime string as type: string in the OpenAPI/Swagger spec instead.
