Implement get_modified_time?

[euven]

When running manage.py collectstatic, I notice that the remote files in Swift, is deleted and re-uploaded every time, even if the files are identical.

Is there any reason you haven't implemented get_modified_time: https://github.com/django/django/blob/stable/5.1.x/django/core/files/storage/base.py#L199 ?

Thanks for this module, it works well! :)
