## プロジェクトの歴史と使われ方

bttf is a Rust command-line tool by BurntSushi for datetime parsing, formatting, arithmetic, time zones, durations, sequences, and pipeline-friendly transformations. It is young, but it sits in a familiar package niche: small CLIs that make date/time work scriptable.

### プロジェクトの歴史

The first public release was published in May 2025 under the name Biff. The project README notes that it was later renamed to bttf, and the 0.1.4 release describes itself as the first release after that rename.

The project is built around a structured command model: bttf time, bttf span, and bttf tz subcommands cover actions such as formatting, arithmetic, rounding, sequencing, sorting, and time-zone lookup.

### 採用の歴史

Adoption is early and package-manager-oriented. The input metadata lists Homebrew and Nix packaging, while the upstream README also publishes precompiled archives and a crates.io package.

Its likely adopters are shell users, Rust users, log wranglers, and developers who need a more careful date/time CLI than basic date(1) pipelines.

### 使われ方

bttf can print the current time, parse RFC 2822/RFC 3339/RFC 9557/ISO 8601 and relative datetimes, add or subtract spans, round durations, generate date sequences, convert time zones, and tag pipeline input so transformed timestamps can be joined back to original lines.

The README documents BTTF_LOCALE as an environment variable affecting locale support, but no persistent config or credentials file is documented.

### パッケージ好きにとっての重要性

bttf is interesting less for age than for taste: it brings modern Rust datetime handling, rich timezone semantics, locale-aware formatting, static binary releases, Homebrew, Nix, and crates.io distribution to the humble date CLI problem.

For package maintainers, the rename from Biff to bttf is a useful bit of provenance because early release artifacts and history may still mention the old name.

### タイムライン

- 2025: Initial 0.1.0 release published as Biff.
- 2026: Project renamed from Biff to bttf.
- 2026: bttf 0.1.4 published as the first release after the rename.

### Related projects

- Jiff is the Rust datetime ecosystem context associated with BurntSushi's date/time work.
- date(1) and GNU coreutils date are the traditional Unix tools bttf complements.
- crates.io distributes the Rust package, while Homebrew and Nix package the CLI for system users.
