This is exactly the point: a string is just a data interchange format in the context of a DateTime, and C# provides (as far as I can tell) a complete way of accessing the ISO-8601 specification on the language object. It also supports type-safe generation of clients and client object (or struct) generation from the ISO-8601 string format.

> And even past that, there are Windows-specific idiosyncrasies with how the `DateTime` class implements the parsing of these strings and how it stores the resulting value.

Not really. The windows statements on the article (and I use this on linux for financial services software) are related to automated settings of the preferences for generated strings. All of these may be set within the code itself.
