TL;DR
Biff is a command line tool designed for datetime arithmetic, parsing, and formatting, offering a wide range of features in a single utility. It is aimed at developers and system administrators needing advanced date/time handling.
A new command line tool named Biff has been launched, offering a comprehensive suite of datetime operations including arithmetic, parsing, formatting, and more. This development is significant for developers, sysadmins, and power users who require advanced date and time handling directly from the terminal.
Biff is a command line utility licensed under MIT or UNLICENSE, designed to handle various datetime tasks efficiently. It supports operations such as printing the current time in different formats and locales, adding durations, calculating durations since specific dates, and transforming timestamps within log files. The tool is built in Rust and is available via precompiled binaries for Windows, macOS, and Linux, or through the Rust package manager Cargo.
Examples of its capabilities include formatting the current time in RFC3339, calculating relative times like ‘next Saturday,’ rounding times to specific intervals, and generating sequences of dates such as the last weekday of each month or the second Tuesday of each month. It also integrates with Git to fetch the last commit dates for files, reformatting them for analysis or reporting.
Why It Matters
This tool matters because it consolidates many datetime operations into a single command line utility, reducing the need for multiple scripts or tools. It can streamline workflows in software development, system administration, and data analysis by providing a versatile, scriptable solution for date and time manipulation directly in the terminal.
Its availability and features could influence how developers and sysadmins handle time-related tasks, especially in automation and logging contexts, making datetime operations more accessible and less error-prone.

Background
Datetime manipulation tools are common in programming and system administration, but many are limited or require multiple utilities. Biff aims to unify these functionalities into one tool, similar to how Swiss army knives serve multiple purposes. It is part of a trend toward more powerful CLI tools built in Rust, emphasizing performance and cross-platform compatibility.
Prior tools often focused narrowly on specific tasks, such as date formatting or timezone conversions. Biff’s broad feature set, including relative time calculations, sequence generation, and log timestamp reformatting, positions it as a comprehensive solution for complex datetime workflows.
“Biff is designed to be a Swiss army knife for datetime operations, combining many functionalities into a single, easy-to-use CLI tool.”
