SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Shifts git commit timestamps to appear as if work was done during specific time windows (e.g., evenings, weekends), while preserving commit content and order.

Core Features & Use Cases

Preserve Content & Order: Keeps messages and authorship intact; only timestamps change.
Backup & Audit: Creates backups of original timestamps for restoration.
Flexible Windows: Supports evenings, weekends, mornings, lunch hours, or custom ranges.
Implementation Guidance: Recommends git filter-branch or git filter-repo with environment date changes.

Quick Start

Example: Shift all commits on the current branch to evenings (19:30–02:00) using the included workflow and backup originals for restoration.
