i've encountered a problem using the GetListing() method. If the Server has "MDTM" support it is not possible to use the modified values of the servers file-listing.
I can force to receive the modified values calling .GetListing("/",FtpListOption.Modify), but this is very slow on large listings and it is depending on the latency of the network.
A FtpListOption to force the usage of the modified values of the servers file-listing would be very nice. Perhaps it is even better to use the inaccurate modified values of the servers file-listing and then to override this values if "FtpListOption.Modify"
