            Bug ID: 41194
           Summary: SetFileTime does not set timestamp on ntfs-3g mounts
           Product: Wine
           Version: 1.9.16
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2

          Assignee: wine-bugs(a)winehq.org
          Reporter: wine.severach(a)spamgourmet.com
      Distribution: ---

To change file times:
Total Commander Wine: Files, Change Attributes
Double Commander: Files, Change Attributes
Linux Shell: touch -r, touch -d, touch -t

File time changes from TC are applied VFAT and ext mounts. File time changes
from TC are ignored on NTFS mounts. Linux touch and Double Commander are able
to change the file time on NTFS mounts.

I think this is a bug in ntfs-3g. Wine doesn't do anything special, see the
function set_file_times in dlls/ntdll/file.c for details.

Note that Double Commander uses the utime syscall, which also works from Wine,
but it isn't used because it has only second precision, and the Windows API has
precision of 100 ns.

That said I have no idea why 'touch' works but Wine doesn't. I did a strace and
the syscalls were identical, and both succeeded, and yet only 'touch' works
because Wine's was simply ignored. It's probably a bug in ntfs-3g related to
the file descriptor open mode/permissions maybe? I didn't look more into it,
because it doesn't seem like a Wine bug to me.

Also the ntfs-3g forums don't allow registration right now, so I've no idea how
to report it there.

Confirming but I don't think this is Wine's bug.
