Set a Remote File's Creation Time

Demonstrates the Chilkat SFtp.SetCreateTimeStr method, which sets a remote file's creation date and time. The arguments are the remote path (or handle), whether the first argument is a handle, and an RFC 822 formatted date/time string such as Fri, 21 Nov 1997 09:55:06 -0600.

Background: Setting timestamps matters when preserving a file's original chronology — migrating an archive, restoring a backup, or mirroring a directory so the copies look identical to the source. Whether creation time can actually be set depends on the server and filesystem; many do not support a settable creation time even when they can set the modified and accessed times. The RFC 822 format includes a timezone offset, so the moment is unambiguous.
