I.e. type.instanceOf(CalendarDate).or(type.instanceOf(CalendarDateTime).or(type.instanceOf(ZonedDateTime).as<DateValue>() (and I'd make DateValue a type import again for clarity)

Type '"DateValue | undefined"' is not assignable to type '"'DateValue' is unresolvable "'.ts(2322)

So you'll need to recreate from the actual classes

Oh, right, DateValue is a type not a class

Using a different name should work though (make sure to update the other references)

Right yeah, the import isn't type-only anymore so you can't name the ArkType type the same

Yeah, there is, so something like

import { DateValue } from "..."; // NB: NOT a type import
import { type } from "arktype";

const DateValue = type.instanceOf(DateValue);

export const arcEditObject = type({
    ...
    start: [DateValue, "|", "undefined"]
});

import { DateValue } from "..."; // NB: NOT a type import
import { type } from "arktype";

const DateValue = type.instanceOf(DateValue);

export const arcEditObject = type({
    ...
    start: [DateValue, "|", "undefined"]
});

should work

Well, actually, I think there's a type.instanceOf or something

Right... I guess you'd need an equivalent ArkType type for each of those classes then

I.e.

import type { DateValue } from "...";
import { type } from "arktype";

const DateValue = type(...).as<DateValue>();

export const arcEditObject = type({
    ...
    start: [DateValue, "|", "undefined"]
});

import type { DateValue } from "...";
import { type } from "arktype";

const DateValue = type(...).as<DateValue>();

export const arcEditObject = type({
    ...
    start: [DateValue, "|", "undefined"]
});
