git怎麼修改commit時間

在git中，可以利用「git commit --amend」指令來修改commit時間；該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，語法為「GIT_COMMITTER_DATE="時間" git commit --amend --date="時間"」。

本文操作環境：Windows10系統、Git2.30.0版、Dell G3電腦。

git怎麼修改commit時間

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

註:日期格式須為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，可以使用互動式rebase：

• #執行git rebase -i COMMIT_SHA ， 此COMMIT_SHA為待修改日期的commit的前一個commit的commit sha

• 在vi彈出交互信息中將待修改日期的commit前的pick修改為e

• 執行日期修改指令GIT_COMMITTER_DATE="2017-10-08T09:51:07" git commit --amend --date="2017-10- 08T09:51:07"

• 執行git rebase --continue轉到下一個commit

• 重複此過程，直到修改所有提交。透過git status可查看進展。

3.修改範例

目前git log提交資訊如下

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

假設此時需要修改6b98331 modify Readme. md 2這一commit的作者日期和提交者日期

修改步驟為:

執行互動式變基指令git rebase -i 98ddd80

在彈出的vi編輯資訊中，將6b98331提交前的pick修改為e，隨後執行:wq 儲存

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.

執行GIT_COMMITTER_DATE="2021-10-22T15:10:07" git commit --amend --date="2021 -10-22T15:10:07" 將作者日期和提交者日期均修改為2021-10-22T15:10:07。然後可選擇在彈出的vi資訊編輯窗中可修改提交日誌，然後執行 :wq 儲存

然後執行 git rebase --continue到下一個提交，直到儲存所有修改。完成後再使用git log查看提交資訊即可看到提交資訊已被修改

上述範例的完整日誌如下:

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
admin@DESKTOP-PC MINGW64 /e/TestProj/ModifyTimeTest (master)
$ git rebase -i 98ddd80
Stopped at 6b98331...  modify Readme.md 2
You can amend the commit now, with
  git commit --amend
Once you are satisfied with your changes, run
  git rebase --continue

$ GIT_COMMITTER_DATE="2021-10-22T15:10:07" git commit --amend --date="2021-10-22T15:10:07"
