It is part of the small but persistent Unix tradition of wrapping tzdb names in more human-friendly command-line interfaces. ### Project history 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. ### Adoption history 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. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 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. ### Sources - - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
