This problem is related to FSharp.Data version 3.3.3.

I am trying to create XmlProvider from XSD but it fails on parsing xs:dateTime values. When trying to access the property, I am getting an error System.Exception: Expecting DateTimeOffset in Value, got 2020-01-20T12:15:00

The same problem happens when accessing XML Values and when accessing XML Attributes.

See the minimal example below.

Is there some workaround or setting that I am missing or is this a bug?

thank you.

open FSharp.Data

type Person = XmlProvider<Schema = """
