rsync-大小，内容，所有者，组，权限，时间相同-仍要复制

Question

rsync-大小，内容，所有者，组，权限，时间相同-仍要复制

使用macOS Mojave。在源目录中使用默认文件系统（每个apfs使用df？），在目标目录中使用FAT32（每个msdos使用df）。

用尽所有想法。

尝试添加--modify-window=1。在rsync手册页中：

--modify-window
          When  comparing  two  timestamps, rsync treats the timestamps as
          being equal if they differ by no  more  than  the  modify-window
          value.   This  is  normally  0 (for an exact match), but you may
          find it useful to set this to a larger value in some situations.
          In  particular,  when  transferring to or from an MS Windows FAT
          filesystem (which represents times with a 2-second  resolution),
          --modify-window=1 is useful (allowing times to differ by up to 1
          second).
