@tef I don't think so either, but I was hoping there was a loophole I wasn't aware of. Like maybe they're rfc3339 or something? Perhaps a foolish hope.
@glyph @tef you want rfc 9557 which adds olson zone names in square brackets as a suffix on rfc 3339 timestamps like 2025-05-06T01:23:45+00:00[Europe/London] https://www.rfc-editor.org/info/rfc9557
