git怎么修改commit时间

在git中，可以利用“git commit --amend”命令来修改commit时间；该方法既可以修改最近一次提交的日期，也可以修改指定某次提交的日期，其中日期的格式需要是“ISO-8601”格式，语法为“GIT_COMMITTER_DATE="时间" git commit --amend --date="时间"”。

本文操作环境：Windows10系统、Git2.30.0版、Dell G3电脑。

git怎么修改commit时间

1.修改最近一次提交的作者日期和提交者日期

如果要修改最近一次commit的作者日期和提交者日期，直接使用 git commit --amend即可

注:日期格式须为ISO-8601格式

GIT_COMMITTER_DATE="2017-10-08T09:51:07" git commit --amend --date="2017-10-08T09:51:07"

2.修改某次提交的作者日期和提交者日期

如果要更改某次(可以是最近一次也可以是非最近一次)提交的作者日期和提交者日期，可以使用交互式rebase：

• 执行git rebase -i COMMIT_SHA ， 此COMMIT_SHA为待修改日期的commit的前一个commit的commit sha

• 在vi弹出交互信息中将待修改日期的commit前的pick修改为e

• 执行日期修改命令 GIT_COMMITTER_DATE="2017-10-08T09:51:07" git commit --amend --date="2017-10-08T09:51:07"

• 执行 git rebase --continue转到下一个commit

• 重复此过程，直到修改所有提交。 通过git status可查看进展。

3.修改示例

当前git log提交信息如下

admin@DESKTOP-PC MINGW64 /e/TestProj/ModifyTimeTest (master)
$ git log --oneline
2fe64c4 (HEAD -> master) modify Readme.md 3
6b98331 modify Readme.md 2
98ddd80 modify Readme.md 1
fcfc064 add Readme.md

假设此时需要修改 6b98331 modify Readme.md 2这一commit的作者日期和提交者日期

修改步骤为:

执行交互式变基命令 git rebase -i 98ddd80

在弹出的vi编辑信息中，将 6b98331提交前的pick修改为e，随后执行 :wq 保存

e  6b98331 modify Readme.md 2      # 此处原为pick,将pick修改为e / edit
pick 2fe64c4 modify Readme.md 3
# Rebase 98ddd80..2fe64c4 onto 98ddd80 (2 commands)
#
# Commands:
# p, pick <commit> = use commit
# r, reword <commit> = use commit, but edit the commit message
# e, edit <commit> = use commit, but stop for amending
# s, squash <commit> = use commit, but meld into previous commit
# f, fixup <commit> = like "squash", but discard this commit&#39;s log message
# x, exec <command> = run command (the rest of the line) using shell
# b, break = stop here (continue rebase later with &#39;git rebase --continue&#39;)
# d, drop <commit> = remove commit
# l, label <label> = label current HEAD with a name
# t, reset <label> = reset HEAD to a label
# m, merge [-C <commit> | -c <commit>] <label> [# <oneline>]
# .       create a merge commit using the original merge commit&#39;s
# .       message (or the oneline, if no original merge commit was
# .       specified). Use -c <commit> to reword the commit message.
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.

执行 GIT_COMMITTER_DATE="2021-10-22T15:10:07" git commit --amend --date="2021-10-22T15:10:07" 将作者日期和提交者日期均修改为2021-10-22T15:10:07。然后可选择在弹出的vi信息编辑窗中可修改提交日志，然后执行 :wq 保存

然后执行 git rebase --continue转到下一个提交，直到保存所有修改。完成后再使用git log查看提交信息即可看到提交信息已被修改

上述示例的完整日志如下:
