date of the transferred file is not preserved

Dear Support Team
The Preserve timestamp checkbox makes WinSCP preserve the last modification timestamp of the transferred file. However, that is not true. When I'm using FileZilla, it works!
WinSCP Version 5.13.6, SFTP
Best regards

Re: date of the transferred file is not preserved

Please 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.

Re: date of the transferred file is not preserved

Thanks for the log. Can you set logging level to "Debug 2" and post a new log file?
Though it actually looks like a server-side problem. From the log, it looks like WinSCP correctly asked for timestamp update.

WinSCP 5.13.7 set to Debug 2: just transferred pdf.gif.
With FileZilla 3.40.0 the date of the transferred file is correct!

This is a correct request by WinSCP to set a timestamp of a file /biochem/httpdocs/Datenbank/php/font/pdf.gif to 1219770987 (‭48B43A6B‬, 2008-08-26T17:16:27+00:00).

The server confirmed the request:
< 2019-01-29 17:30:06.091 Type: SSH_FXP_STATUS, Size: 26, Number: 2057
< 2019-01-29 17:30:06.091 65,00,00,08,09,00,00,00,00,00,00,00,07,53,75,63,63,65,73,73,00,00,00,02,65,
< 2019-01-29 17:30:06.091 6E,
< 2019-01-29 17:30:06.091 Status code: 0

Please report the problem to your server vendor. Actually, what SFTP server is that? It reports as OpenSSH, but uses SFTP version 5, what OpenSSH does not support. So it must be some proprietary server.

Thank you very much for your work!
However, why the transfer with FileZilla works with this server?

I do not know. The server bug may manifest only in some very specific situations.
For example FileZilla uses SFTP version 3. While WinSCP is capable of SFTP up to version 6.
You can try forcing WinSCP to use version 3:

Great hint! It works! Thanks a lot for your help!
I informed the webmaster of the server too.
