Hi CAZ,
joedayney here (Logan Utah USA)
Yes it is an old problem ... see this article
https://www.codeproject.com/articles/Beating-the-Daylight-Savings-Time-Bug-and-Getting
It looks like the next release will fix this bug
https://winscp.net/eng/docs/history
In the meantime ... go to WinSCP Login (for each saved session profile) click on
Environment ... change from default setting for DST ... to
"Server adjusts DST" so your "make" files ... etc will work. WinSCP view will be off by 1 hour but the actual time in Server will be correct. If you use WinSCP / Notepad++ and save the file ... otherwise the file will save wrong. By Using the Setting Change so that the "Server" DST time is used ... your Server File will be correct.
Try it and let me know if that helps. Cheers!
