Version:0.18.2
Archive:TestArchives\Archives\Zip.deflate.zip

Below is the code i used. The extract files` modifiled time just like the create time rather than the modifiled time of original file.

using (archive = ArchiveFactory.Open(path,
    new ReaderOptions { ArchiveEncoding = new SharpCompress.Common.ArchiveEncoding { Default = Encoding.Default } }))
{
    archive.WriteToDirectory(expath,
        new ExtractionOptions
       {
            ExtractFullPath = true,
            Overwrite = true
       });
 }

Sorry, I think you'll have to be more specific.

The modified time of the extracted file matches the create time instead of using the last modified time from the zip?

Finally I found the option "PreserveFileTime", it solved my question.
