ISO8601 is really broad with loads of edge cases and differing versions. RFC 3339 is closer, but still with a few quirks. Not sure why we can't have one of these that actually has just one way of representing each instant.

I love how that's live!

Since ISO 8601 costs 133 CHF I suspect hardly anybody has actually read it, I think if you wanted something that supports all the weird stuff you might find somebody wrote it in 390 assembly.
