下面的bash函数将更改当前分支上任何提交的时间。

如果您已经推送了提交，或者在另一个分支中使用提交，请注意不要使用。

# rewrite_commit_date(commit, date_timestamp)
#
# !! Commit has to be on the current branch, and only on the current branch !!
# 
# Usage example:
#
# 1. Set commit 0c935403 date to now:
#
#   rewrite_commit_date 0c935403
#
# 2. Set commit 0c935403 date to 1402221655:
#
#   rewrite_commit_date 0c935403 1402221655
#
rewrite_commit_date () {
    local commit="$1" date_timestamp="$2"
    local date temp_branch="temp-rebasing-branch"
    local current_branch="$(git rev-parse --abbrev-ref HEAD)"

    if [[ -z "$date_timestamp" ]]; then
        date="$(date -R)"
    else
        date="$(date -R --date "@$date_timestamp")"
    fi

    git checkout -b "$temp_branch" "$commit"
    GIT_COMMITTER_DATE="$date" git commit --amend --date "$date"
    git checkout "$current_branch"
    git rebase "$commit" --onto "$temp_branch"
    git branch -d "$temp_branch"
}

    git checkout "$current_branch"
    git rebase "$commit" --onto "$temp_branch"
    git branch -d "$temp_branch"
}

下面是一个方便的别名，它将上一次提交的提交时间和作者时间都更改为date接受的时间——date:

[alias]
    cd = "!d=\"$(date -d \"$1\")\" && shift && GIT_COMMITTER_DATE=\"$d\" \
            git commit --amend --date \"$d\""

使用方法:git cd <date_arg>

例子:

git cd now  # update the last commit time to current time
git cd '1 hour ago'  # set time to 1 hour ago

编辑: 下面是一个更自动化的版本，它检查索引是否干净(没有未提交的更改)，并重用最后的提交消息，否则会失败(万无一失):

[alias]
    cd = "!d=\"$(date -d \"$1\")\" && shift && \
        git diff-index --cached --quiet HEAD --ignore-submodules -- && \
        GIT_COMMITTER_DATE=\"$d\" git commit --amend -C HEAD --date \"$d\"" \
        || echo >&2 "error: date change failed: index not clean!"

修改上次提交的日期和时间的最简单方法

git commit --amend --date="12/31/2021 @ 14:00"

已经有很多很好的答案，但是当我想在一天或一个月内更改多次提交的日期时，我找不到合适的答案。所以我为此创建了一个新的脚本，希望它能帮助到一些人:

#!/bin/bash

# change GIT_AUTHOR_DATE for commit at Thu Sep 14 13:39:41 2017 +0800
# you can change the data_match to change all commits at any date, one day or one month
# you can also do the same for GIT_COMMITTER_DATE

git filter-branch --force --env-filter '

date_match="^Thu, 14 Sep 2017 13+"              

# GIT_AUTHOR_DATE will be @1505367581 +0800, Git internal format 
author_data=$GIT_AUTHOR_DATE;                   
author_data=${author_data#@}                  
author_data=${author_data% +0800}                # author_data is 1505367581     

oneday=$((24*60*60))

# author_data_str will be "Thu, 14 Sep 2017 13:39:41 +0800", RFC2822 format
author_data_str=`date -R -d @$author_data`      

if [[ $author_data_str =~ $date_match ]];
then
    # remove one day from author_data
    new_data_sec=$(($author_data-$oneday))
    # change to git internal format based on new_data_sec
    new_data="@$new_data_sec +0800"             
    export GIT_AUTHOR_DATE="$new_data"
fi
' --tag-name-filter cat -- --branches --tags

日期将有所更改:

AuthorDate: Wed Sep 13 13:39:41 2017 +0800

我创建了这个npm包来更改旧的提交日期。

https://github.com/bitriddler/git-change-date

示例用法:

npm install -g git-change-date
cd [your-directory]
git-change-date

系统将提示您选择要修改的提交，然后输入新的日期。

如果你想通过指定的散列来更改提交，请运行git-change-date——hash=[hash]
