Get Create Date/Time of Files in a Remote Directory

Gets the creation date/times of files in a remote FTP directory.

9.5 Note: Linux and MacOSX filesystems do not keep a file's creation date/time. If the FTP server is running on such as system, then the Chilkat methods to return a creation date/time will instead return a last-modified date/time.

Also Note: FTP servers have differing capabilities. The "MLSD" command is not supported by all FTP servers. For such servers, only the last-modified date/time is returned per file or directory. Also, the precision of the date/time can vary.

Also, even if MLSD is supported, the server may not return "create" times. A sample MLSD response without "create" times is shown here:

The original creation time of a file is only available if the "create" fact is returned in the MLSD response. See RFC 3659 - Format of Facts / Standard Facts
