>>I thought the same way and looked it a little bit today. Though it sounded really weird to me here is what I have found. You use ListDirectoryDetails and parse the datetime part. But if it is in current year, directory listing has hour:minute instead of a year. If it is in another year then it lists the year. Here is a listing w/o parsin further:

And here is the list I got:

Strangely you can see entries in future.

Here is the more detailed version that I promised:

using System;
using System.Linq;
using System.Net;
using System.IO;

namespace CBSample

    class FtpSmaple
    {
        void Main()

            Uri uri = new Uri(baseUri);
            FtpWebRequest req = (FtpWebRequest)FtpWebRequest.Create(uri);
            req.Proxy = null;
            req.Credentials = new NetworkCredential("anonymous", "password");
            req.Method = WebRequestMethods.Ftp.ListDirectoryDetails;

            string files;
            using (FtpWebResponse resp = (FtpWebResponse)req.GetResponse())
            using (Stream stream = resp.GetResponseStream())
            using (StreamReader reader = new StreamReader(stream))
            {
                files = reader.ReadToEnd();
            }

            foreach (var file in files.Replace("\r", "").Split('\n'))
            {
                string fName = file.Split(' ').Last();
                bool isDirectory = file.StartsWith("d", true, null);
                if (!fName.StartsWith(".") && fName != "")
                {
                    MyInfo info =
                           GetFileInfo(baseUri, fName);
                    Console.WriteLine("{0,-10}: {1,-30} | Modified: {2:yyyy/MM/dd HH:mm:ss}",

                              info.FileName,
                              info.LastModified);
                }
            }
        }

        private MyInfo GetFileInfo(string baseuri, string fileName)
        {
            MyInfo result = new MyInfo();
            result.FileName = fileName;
            Uri uri = new Uri(String.Format("{0}/{1}", baseuri, fileName));
            FtpWebRequest req = (FtpWebRequest)FtpWebRequest.Create(uri);

            req.Proxy = null;
            req.Credentials = new NetworkCredential("anonymous", "password");
            req.Method = WebRequestMethods.Ftp.GetDateTimestamp;
            using (FtpWebResponse resp = (FtpWebResponse)req.GetResponse())
            {
                result.LastModified = resp.LastModified;
            }
            return result;
        }
    }

    class MyInfo
    {
        public string FileName;
        public DateTime LastModified;
    }
}
