Get a Remote FTP File's Last-Modified Time by Name

Demonstrates the Chilkat Ftp2.GetLastModifiedTimeByNameStr method, which returns the last-modified time of a named item in the current remote directory as an RFC 822 date-time string. The only argument is the filename.

Background: This queries one item's modification time directly (typically via MDTM) rather than pulling and scanning a whole listing — efficient when you already know the filename and just need its timestamp, for example to decide whether a local copy is stale. The RFC 822 string includes a timezone offset, so the moment is unambiguous.
