In Mountain Duck 2.2.1 and Cyberduck 6.3.1, timestamps are still not being applied with Cryptomator WebDAV mounts. If I mount a Cryptomator WebDAV URL in Mountain Duck, any copied file displays the correct modification date on the share until it is dismounted. After the share is dismounted (or if you view it from the Cryptomator mount point), the timestamp reverts to showing when it was added to the folder rather than the date modified. It is never correct in Cyberduck, even with "preserve modification timestamp" checked. Fairly certain this issue is not on Cryptomator's end since it works as intended with the Cryptomator mount point.
