Biff is a command line datetime Swiss army knife

The developer of Biff, a command line utility for datetime operations, announced its availability, offering a versatile tool for parsing, formatting, and manipulating dates and times directly from the terminal.

Biff is an open-source command line tool licensed under MIT or UNLICENSE, designed to handle a wide range of datetime tasks. It supports operations such as printing the current time in various formats, converting between time zones, adding durations, calculating time spans, and reformatting timestamps in log files. The tool can generate sequences of specific weekdays, find the last weekday of each month, and retrieve the latest commit dates from git repositories. Biff is available as a precompiled binary for Windows, macOS, and Linux, or can be installed via Rust’s cargo package manager with optional locale support. Its documentation includes numerous examples illustrating its capabilities, aiming to serve as a Swiss army knife for datetime-related tasks in command-line environments.

Why It Matters

This development matters because it introduces a unified, flexible tool for managing date and time operations in scripting, logging, and system administration. It can streamline workflows that involve complex datetime calculations, timezone conversions, or log analysis, potentially replacing multiple specialized tools. For developers and sysadmins, Biff offers a programmable, scriptable solution that could improve efficiency and accuracy in handling temporal data.

Background

Existing tools for datetime manipulation on the command line are often fragmented, requiring multiple utilities or custom scripts. Biff aims to consolidate these functionalities into one tool, inspired by the need for a comprehensive, easy-to-use command line utility. Its features resemble those of other datetime tools but with an emphasis on versatility and ease of use. The project is relatively new, with initial documentation and examples now available, indicating ongoing development and potential for further features.

“Biff is designed to be a Swiss army knife for datetime operations, supporting a wide range of commands from formatting to timezone conversions.”
