Not exactly what's in this original post but here's a little shell function that could be useful to conveniently backdate Git commits: dated() { date=$

  If all you want is author date (which I think is more correct), then just this works fine: git commit --date '1990-01-01 10:10'

    IIRC the GitHub UI started showimg commit date instead of author date some years ago.

  I use the following to create a commit using the latest modification date of the staged files. If you put it in your PATH as git-tcommit, you can invoke it as `git tcommit`. If GIT_AUTHOR_DATE or GIT_COMMITTER_DATE is passed, it overrides the modified time, and it honors TZ. It works with GNU or BSD. #!/usr/bin/env bash set -eEuo pipefail # `git commit`, using the latest file modification time as the commit and author # dates, when GIT_AUTHOR_DATE or GIT_COMMITTER_DATE, respectively, is not set. # Use fractional seconds when available to display the newest file more # accurately, even though Git only uses seconds. if which gstat >/dev/null; then stat=(gstat --format='%.Y %n') # Detected aliased GNU coreutils elif stat --version 2>/dev/null | grep -q 'GNU coreutils'; then stat=(stat --format='%.Y %n') # Detected GNU coreutils else stat=(stat -f '%m %N') # Fallback to BSD-style, which only reports seconds fi # Select the latest modified time of all staged files, excluding deletions. modified="$( cd "$(git rev-parse --show-toplevel)" && git diff --staged --diff-filter=d --name-only -z | xargs -0 "${stat[@]}" | sort -rn | head -1 )" modified_seconds= if [[ -n $modified ]]; then modified_seconds="${modified%% *}" modified_file="${modified#* }" modified_date="$(date -r "${modified_seconds%.*}" +'%Y-%m-%d %H:%M:%S %z')" echo "Modify date: $modified_date ($modified_file)" fi author_seconds="$modified_seconds" committer_seconds="$modified_seconds" if [[ -n ${GIT_AUTHOR_DATE+.} ]]; then echo "Author date: ${GIT_AUTHOR_DATE:-now}" fi if [[ -n ${GIT_COMMITTER_DATE+.} ]]; then echo "Commit date: ${GIT_COMMITTER_DATE:-now}" else last_commit_seconds="$(git show -s --format=%at HEAD 2>/dev/null || echo 0)" if [[ $modified_seconds < $last_commit_seconds ]]; then committer_seconds= echo "Commit date: now (last commit: $(git show -s --format=%ai HEAD 2>/dev/null))" fi fi GIT_AUTHOR_DATE="${GIT_AUTHOR_DATE-"$author_seconds"}" \ GIT_COMMITTER_DATE="${GIT_COMMITTER_DATE-"$committer_seconds"}" \ exec git commit "$@"
