将文件修改时间改为创建时间

我有一个通过 webdav 提供文件的 apache web 服务器（Ubuntu 18.04.5，Apache 2.4.29，启用了 mod_dav）

我使用 chmod 修改了所有文件的权限，现在网络服务器返回了错误的创建日期（已更改而不是已创建）

<lp1:creationdate>2020-11-12T07:02:01Z</lp1:creationdate>
<lp1:getlastmodified>Mon, 12 Oct 2020 05:50:52 GMT</lp1:getlastmodified>

这肯定是 apache webdav 模块的一个错误。糟糕的是，因为我使用 webdav 服务器为我的客户端执行备份。现在，如果客户端尝试恢复备份，所有备份都具有相同的时间戳，他无法分辨哪个是正确的。

作为快速修复，如何将文件ctime值更改为crtime（或mtime）

这里有一些调试信息可以确认这种情况发生了。
