Move existing commit times into chosen daily working hours.

Usagegit-wrangler rewrite-hours --window <schedule> [options]

Warning: This rewrites Git history. Coordinate with collaborators and use git-wrangler push --force when publishing the result.

Quick start

git-wrangler rewrite-hours --window 09:00-17:00

What it does

rewrite-hours keeps each selected commit on its current calendar date while moving its author and committer time into a chosen same-day window.

Use one window for every day, or provide a weekday schedule. With a schedule, commits on omitted weekdays stay unchanged.

Window formats

# Every day
git-wrangler rewrite-hours --window 09:00-17:00

# Weekdays and Saturday; Sunday stays unchanged
git-wrangler rewrite-hours \
  --window mon-fri=09:00-17:00,sat=10:00-14:00

Each start time must be earlier than its end time.

Before you run it

git-filter-repo is required. Git Wrangler records changed commits so rollback-rewrites can restore them later.
