[quote="pshute"]I'm regularly uploading files to a site, and the uploaded files get a timestamp of the current time but in another time zone, which is 5 hours behind mine. I'm using the "put -neweronly ..." command (with winscp.com v5.13.7 build 9125), but some (not all) previously uploaded files get uploaded every time.

I think this is because if I upload a file less than 5 hours old, its local time stamp will appear newer than the remote one forever.

Is there a way around this?

The two uploads are inconsistent, because the first time, there's no file in the target server, and WinSCP cannot detect timezone difference. While second time, there's the previously uploaded file, which WinSCP uses to detect the difference.

You can fix that by explicitly telling WinSCP what the timezone offset is:

How does this look? The log file shows the results of connecting and uploading two files twice in a row, the first time to an empty directory.

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

To generate the session log file, use /log=path_to_log_file command-line argument. 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.
