An implementation of the [TAI64(N)] (*Temps Atomique International*) timestamp
format in Rust.

[Documentation][docs-link]

## Minimum Supported Rust Version

Rust **1.56** or newer.

In the future, we reserve the right to change MSRV (i.e. MSRV is out-of-scope
for this crate's SemVer guarantees), however when we do it will be accompanied by
a minor version bump.
