I've been using the Keep remote directory up to date option a lot, but a few days ago it just seemed to stop working.
Now *all* the files are uploaded *every* time :-(
The problem started around the change to Daylight Saving here in the UK, and the file timestamps are reported by WinSCP as an hour out. However, this also coincided with my server's IP address being changed and host lookup getting broken for a while, not to mention moving from WinSCP 3.3 to the latest release!
The remote server clock was actually a couple of hours out, so the timestamp isn't being set remotely.
I've tried copying all of the files with Preserve Timstamp set on, but that didn't change anything.
Anyone got any ideas?
