Date and DateTime Validation

[jmc420]

I cannot get the Date or DateTime scalars to work. I can see why it is not working because the REGEX is rejecting the string being producted by JSON.stringify. I'm am creating an input object with a Date field that is initialised with new Date(). In the fetch the JSON.stringify converts the date object into "2023-08-31T16:57:53.991Z".

If I pass a Date with the format: "2023-08-31T16:57:53.991Z" to either the Date or DateTime scalars, the REGEX expressions in validator.js fails.

In validateDate the REGEX is

const RFC_3339_REGEX = /^(\d{4}-(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01]))$/;

in ValidateDateTime the REGEX is:

const RFC_3339_REGEX = /^(\d{4}-(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01])T([01][0-9]|2[0-3]):([0-5][0-9]):([0-5][0-9]|60))(.\d{1,})?(([Z])|(+|-:[0-5][0-9]))$/;

This REGEX works fine:

const RFC_3339_REGEX = /^((?:(\d{4}-\d{2}-\d{2})T(\d{2}:\d{2}:\d{2}(?:.\d+)?))(Z|[+-]\d{2}:\d{2})?)$/;

(see https://regex101.com/r/qH0sU7/1).

Is this a fault with the vaildation REGEX or with the way I am using the scalars?

Agreed, it's baffling that DateTime can't parse any of the built-in string formats supplied by Javascript's own Date!
