OpenApi string field with format date has bad path in generated typescript

[bhoudu]

There is an error on the path generated :

import { DateFromISODateStringIO } from '../utils/utils';

And it should be :

import { DateFromISODateStringIO } from '../../utils/utils';

After toying with quick fixes, it seems, DateFromISODateStringIO should not be generated at all in utils.

I feel the io-ts implementation is what is required :

import { DateFromISOString } from 'io-ts-types/lib/DateFromISOString'

The DateFromISODateStringIO codec was made to accommodate the specified date data type instead of date-time which is covered by io-ts's DateFromISOString.

The reason is that the Date object in JS always represents date-time. There is no specific object which would work with dates separately but there is a Date(year, month, day) constructor which omits the time information that will always be present if you try to create a Date instance using ISO string constructor. Specifically, if you don't specify the time it will be set as 00:00 UTC which is not the desired behavior when you work with dates only.

The DateFromISOString codec, on the other hand, always uses ISO constructor and can't be used to represent the date data type because of the described behavior.
