Option to not set last-modified time.
When using a GUI file manager I am typically not expecting perfect preservation of data and metadata. This preservation can be annoying when extracting a file or two to a folder that I then view sorted by "last modified". I expect the newly created file to be at the top but due to metadata preservation it is somewhere else in the list.
For me personally I would like to have a config option to disable preserving the last modified timestamp of top-level items. This way the top level items will sort correctly in a folder I extract them to but nested directories will keep whatever timestamps. (Although I don't care much about this, I would be fine with no timestamp preservation)
Some people may prefer to preserve the timestamps, so I think this should be configurable.
