Is there a way to parse Dates and date iso strings without losing toJsonSchema capabilities.

I'm trying to parse dates and also allow for date objects, but I also require toJsonSchema to work without exceptions.

const dateParse = type("string.date.iso.parse");
const date = new Date();
dateParse(date) // error
dateParse(date.toISOString()) // works
dateParse.in.toJsonSchema() // works

const dateParse2 = type("string.date.iso.parse | Date");
const date = new Date();
dateParse2(date) // works
dateParse2(date.toISOString()) // works
dateParse.in.toJsonSchema() // errors

const dateParse = type("string.date.iso.parse");
const date = new Date();
dateParse(date) // error
dateParse(date.toISOString()) // works
dateParse.in.toJsonSchema() // works

const dateParse2 = type("string.date.iso.parse | Date");
const date = new Date();
dateParse2(date) // works
dateParse2(date.toISOString()) // works
dateParse.in.toJsonSchema() // errors

Is there a way to have all three functionalities combined? It is fine if the json schema only shows the string input.

I don't want to convert date -> string -> date if possible and also keep only one schema.
