## プロジェクトの歴史と使われ方

tz is an interactive terminal helper for comparing times across selected IANA time zones. It is part of the small but persistent Unix tradition of wrapping tzdb names in more human-friendly command-line interfaces.

### プロジェクトの歴史

The oz/tz repository was created in January 2021. Its README presents the program as an interactive TUI for scheduling across time zones, displaying local time, UTC, and user-chosen zones.

The release history shows a fast early 2021 series through 0.6, then later releases in 2023, 2024, and 2025. The README documents a configuration file, an environment-variable workflow through `TZ_LIST`, command-line arguments, and Go source builds.

### 採用の歴史

The README lists Homebrew and Arch packaging and `go install`; the batch package facts add apk and Nix. This is typical adoption for a small Go terminal app that solves a daily coordination problem for distributed teams.

Its adoption depends on the IANA time zone database naming scheme: users pass zone names such as `Europe/Paris` or `US/Pacific`, and the tool renders those names into local-time comparisons.

### 使われ方

Typical use is to run `tz` with no arguments for local and UTC time, pass zone names on the command line, set `TZ_LIST` for shell-level defaults, or store preferred zones in `~/.config/tz/conf.toml`.

In package-manager workflows, tz is a lightweight install for people who do not want a calendar app just to answer cross-zone scheduling questions from the terminal.

### パッケージ好きにとっての重要性

tz matters as a small wrapper around tzdb rather than as new time-zone infrastructure. Package nerds care because it shows the value of keeping canonical zoneinfo data in the operating system while packaging focused CLI views on top.

### タイムライン

- 2021-01-30: oz/tz GitHub repository created.
- 2021-03-16: v0.4 released during the early release series.
- 2023-01-16: v0.6.3 released.
- 2025-02-14: v0.8.0 released.

### Related projects

- The IANA Time Zone Database provides the zone names and rules used by tz.
- tzdiff is a related terminal tool for comparing local and remote time-zone columns.
