TL;DR
Biff is a command line tool designed for advanced datetime manipulation, including parsing, formatting, and arithmetic. It aims to serve developers and sysadmins needing versatile date operations.
The developer of Biff, a new command line tool for datetime arithmetic, parsing, and formatting, announced its release today, offering a versatile utility for developers and sysadmins.
Biff is a command line application licensed under MIT or UNLICENSE, designed to handle a broad range of datetime tasks. Its features include printing current time in various formats, timezone conversions, relative time calculations, date sequence generation, and log file timestamp reformatting. The tool is implemented in Rust and available via crates.io or as precompiled binaries for Windows, macOS, and Linux.
According to the developer, Biff’s core functionality is to simplify complex datetime operations that typically require multiple tools or scripting. Examples include generating sequences of specific weekdays, calculating durations since past dates, and extracting timestamps from logs and converting them locally. It supports locale-aware formatting, provided locale support is enabled during installation.
Why It Matters
This development matters because Biff consolidates numerous datetime functions into a single command line tool, potentially streamlining workflows for developers, system administrators, and data analysts. Its open licensing and Rust implementation suggest it is designed for broad adoption and integration into scripting environments.
