Description

Hey,

when generating a parameter with the format 'date', it is falsely converted to 'date-time'. So in my case 'dateFrom' contains a time (e.g. '2019-12-10T17:56:56.999Z'), but should look like this: '2019-12-10'.

openapi-generator version

4.2.2

OpenAPI declaration file content or url

...
- name: date_from
          in: query
          description: >-
            Date parameter to search for ... (format\: \"yyyy-MM-dd\")
          required: false
          schema:
            type: string
            format: date
...

Command line used for generation

openapi-generator generate -i assets/api.yaml -g typescript-rxjs -o src/lib

Steps to reproduce

• Generate the api
• View the dateFrom parameter

As in the typescript-fetch generator, write instead of .toISOString():

.toISOString().substr(0,10) or .toISOString().split('T')[0]
