Git:父提交比后代年轻？

Question

我正在浏览 http://arago-project.org/git/projects/linux-omap3.git repo 并遇到一个奇怪的约会对象，它基本上说父提交比它的 child 小一岁。

这怎么可能？

Answer 1

如评论中所述:

• 您可以在提交上放置您想要的任何时间戳:“git commit - setting timestamps into the future ”
• 您可以修改提交的时间戳:“How can one change the timestamp of an old commit in Git?”
• 您正在处理两个日期:GIT_AUTHOR_DATE 和 GIT_COMMITER_DATE:参见 working with date in Git .

您看到的结果可能是:

• rebase，因为 git rebase 默认情况下实际上不会更改作者的时间戳:请参阅“git rebase without changing commit timestamps”。
• cherry-picking (作为 commented by Michael Anderson )因为它还保留了 GIT_AUTHOR_DATE
