Visual Basic 6.0

Set a Remote File's Last-Access Time

Demonstrates the Chilkat SFtp.SetLastAccessTimeStr method, which sets a remote file's last-access 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.

Background: Setting the access time explicitly is mainly for faithful restores and mirrors, where you want the copy's metadata to match the original exactly. Note that many servers update the access time on their own whenever a file is read (unless mounted noatime), so a value you set can be overwritten by ordinary access — making this the least durable of the timestamps to control.
