Version: (using KDE 4.3.4) OS: Linux Installed from: Ubuntu Packages When you use Dolphin to copy files between directories, usually file date and time are preserved, so the copy has the same date and time than the original. But suppose you want to copy a file from a local machine to a remote one, and you access the remote one through a FISH KIOslave. Then the date and time of the file copies are NOT preserved if you copy *from* LOCAL *to* REMOTE, but surprisingly they ARE preserved if you copy from REMOTE to LOCAL. If you use the SFTP KIOslave, date and time are NOT preserved in any case. This happens even if your "remote" machine is also your local one. This is a very annoying bug that prevents or greatly difficults using those KIOslaves for backup purposes.
Thanks for the bug report! This issue is known already. *** This bug has been marked as a duplicate of bug 55804 ***
