Why can't the metadata of a directory include the last modified time?

[cammette]

When using some file systems, such as local file systems, the metadata of directories generally includes the last modified time. However, in the list of entries traversed by opendal, if the entry is a directory, its last modified time is None.
If I want to obtain the last modified time of a directory, how should I do it?

Your point is correct; we do need to ensure the metadata for directories is accurately filled whenever possible. Let's address this in the next release.

I'd like to have a try.
