Get a Remote File's Creation Time

Demonstrates the Chilkat SFtp.GetFileCreateTimeStr method, which returns a remote file's creation date and time. The arguments are the remote path (or handle), whether symbolic links are followed, and whether the first argument is a handle.

Background: Creation time is the least universally available of the three timestamps: many Unix filesystems historically tracked only modified and accessed times, so a server may return nothing or a placeholder. Where it is supported it is genuinely useful — it does not change when a file is edited, unlike the modified time — but code should tolerate its absence rather than depend on it.
