SYNOPSIS
bttf [*command*] [*options*]
DESCRIPTION
bttf (formerly biff) is BurntSushi’s command-line toolkit for datetime parsing, formatting, arithmetic, and timezone-aware calculations. Designed as a script-friendly companion when date alone is awkward. See the upstream user guide for locale configuration tips.
PARAMETERS
Commands cover parse/format/add/duration-style operations—the surface is intentionally broad. Use bttf --help and per-subcommand help as the source of truth for your version.
INSTALL
brew install bttf
nix profile install nixpkgs#bttf
CAVEATS
Locale support may need explicit configuration for some environments. Previously named biff; update scripts after the rename.
