最初，配置管理工具只是由保存版本的存储库组成：一个文件和目录的内容在给定的时间点上存储和确定，并且在需要时可以重现取回。

Initially, CM tools consisted only of a repository for storing versions: the contents of a file or directory at a given point in time that is stored and identified, and can be retrieved as necessary.

如果不能通过 shell 访问，那么您可以重新加载或进行编辑保存，这样也能更新文件的时间戳。

If you do not have shell access, you can update the timestamp of the file by reuploading it or by editing it and resaving it.
