WinSCP-release-6.1.1: TransferOptions:PreserveTimestamp = TRUE ignored?

I do my first steps with .NET automation.

When uploading files to the FTP-server, I always get the current time as timestamp of the uploaded file.

I upload the files with PutFiles()

Thanks for your help!

The FTP server reports the following features:

Re: WinSCP-release-6.1.1: TransferOptions:PreserveTimestamp = TRUE ignored?

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, set Session.SessionLogPath. 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.

I did an upload to the FTP server (TimeStamp 16:36) and a download shortly after (TimeStamp 16:38).

I had the following transferoptions: 
transferOptions:TransferMode = TransferMode:BINARY.
transferOptions:PreserveTimestamp = TRUE.
I found in the log file part with the download 
2023-08-16 16:38:55.305 Preserving timestamp [2023-08-16T14:35:57.000Z]
There is nothing like this in the upload.

Thanks for your help!

WinSCP requested timestamp update correctly and the server have ignored that. 
> 2023-08-16 16:36:00.530 MFMT 20230810135837 Testftp.txt
...
< 2023-08-16 16:36:00.536 213 Modify=20230816163557; Testftp.txt
So it does seem to be a server-side problem.

Thank you very much for your help.
I asked the owner of the FTP server and she told me that they disabled the function of saving the TimeStamp so they would know the upload time.
