biff is a command-line utility for working with dates, times, durations, and time zones from the shell.
It lets you carry out datetime arithmetic, parse human-friendly temporal expressions, format timestamps in different representations, and handle common command-line time workflows such as calculating spans, generating recurring datetimes, and transforming timestamps in logs.
This is free and open source software.
Key Features
- Generates sequences of datetimes using RFC 5545 recurrence rules.
- Performs calendar and absolute duration arithmetic safely across daylight saving time boundaries.
- Uses the IANA time zone database for timezone-aware conversions.
- Tags arbitrary JSON lines data with datetimes, which is useful for reformatting or localizing log timestamps.
- Compares and sorts datetimes.
