如何更改Git中旧提交的时间戳？ [英] How can one change the timestamp of an old commit in Git?

问题描述

解答如何修改现有的，unpushed提交？描述了一种方法来修改之前尚未推送到上游的提交消息。新消息继承原始提交的时间戳。这似乎是合乎逻辑的，但有没有办法重新设置时间？ 使用 git filter-branch ，并设置了一个env过滤器，它为您希望解决的提交的特定散列设置GIT_AUTHOR_DATE和GIT_COMMITTER_DATE。

例如：

如果您想要更改提交<$的日期 c $ c> 119f9ecf58069b265ab22f1f97d2b648faf932e0 ，你可以这样做：

  git filter-branch --env-filter \ 
'if $ [$ GIT_COMMIT = 119f9ecf58069b265ab22f1f97d2b648faf932e0] ​​
 then 
 export GIT_AUTHOR_DATE =Fri Jan 2 21:38:53 2009 -0800
 export GIT_COMMITTER_DATE =Sat May 19 01:01:01 2007 -0700
 fi'
  

The answers to How to modify existing, unpushed commits? describe a way to amend previous commit messages that haven't yet been pushed upstream. The new messages inherit the timestamps of the original commits. This seems logical, but is there a way to also re-set the times?

解决方案

Use git filter-branch with an env filter that sets GIT_AUTHOR_DATE and GIT_COMMITTER_DATE for the specific hash of the commit you're looking to fix.

This will invalidate that and all future hashes.

Example:

If you wanted to change the dates of commit 119f9ecf58069b265ab22f1f97d2b648faf932e0, you could do so with something like this:

git filter-branch --env-filter \
    'if [ $GIT_COMMIT = 119f9ecf58069b265ab22f1f97d2b648faf932e0 ]
     then
         export GIT_AUTHOR_DATE="Fri Jan 2 21:38:53 2009 -0800"
         export GIT_COMMITTER_DATE="Sat May 19 01:01:01 2007 -0700"
     fi'
