Although I set the timestamp function, I failed to get a timestamp tracking on context (The folder) I also tried Synchronize ,but it doesn't work.

Preserving timestamps is not available with all protocols and servers. For details, see:
https://winscp.net/eng/docs/ui_transfer_custom#common
https://winscp.net/eng/docs/protocols#timestamp
If you need further help, please specify what protocol are you using and attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

The attached file is the log file generated during the SFTP file transfer.

The context option in the gray box is still not working. Directory timestamps cannot be preserved, although file timestamps can be preserved.

You are using SCP protocol. While you have possibly selected SFTP (I cannot tell as you didn't post a complete log file), the server rejects SFTP session. So WinSCP falls back to SCP protocol. With the SCP protocol, preserving directory timestamps is not supported.
