On Monday (today) the time stamps on the remote files (that were created today) showed 1 hour in the future. 3:15 instead of 2:15 (both times are pm. The 2:15 is the correct time)
Closing the session and re-opening cleared the condition. I suspect that time zone offset is only checked at connection?
Using SFTP and WinSCP version 4.0.5 (build 354)
Not a really critical type of problem.
