>Description:
If windows share located on NTFS file system mounted to FreeBSD using mount_smbfs, /usr/bin/stat shows atime, mtime and ctime equal, but realy file have three different times.

If you try to set mtime of file with odd seconds - it will be writen one second less value - even seconds.

When NTFS share mounted to Windows system - all three file time may be different and may have odd seconds in its.
