FFS 8.9 (donation edition) and timestamps when syncing to Synology NAS

[rusinko]

Hello,

i am synching a large documents folder from a Windows 10 computer using FreeFileSync (newester version 8.9 as of today, donation edition) to a Synology NAS that, the synology drive is mounted via Mountainduck and shows up with a normal drive letter in windows.

The synchroniztion settings are configured as "mirror" with no versioning.

Strangely, all the files dates and timestamps are replaced by the current date, rather than the dates/times being picked up from the original files.

I am wondering whether there is an issue with the latest FFS software in this respect? I have used double commander to copy things over and if i do this, then the original filestamps/dates/times are preserved. so this is seemingly not an issue that could come from mountainduck webDAV software.

Any ideas?
thanks
