Option 4: like option 3, but also introduce a leap second table (potentially fetched from the system) to compute durations

Option 5: introduce a TimePoint type, counted in TAI, that can convert from/to DateTime (probably in addition to option 2)

Option 6: like option 5, but make struct DateTime(TimePoint, Tz)

No problem! I tried to make the top-post as easy to digest as possible and requiring no context so it's possible to read it without knowledge of the past discussions...

Random thought: the information could also be written in `Cargo.toml`, and just stripped out of it by `cargo publish` before uploading to the repo? Not sure whether this idea holds...

Even better would be to use `crossbeam-utils`'s `Backoff`, I guess.
