Description Peterr346 2021-03-27 01:09:14 UTC 
Description:

There are users who want to have nanoseconds in stat command, because these users use file systems like ZFS which internally stores nanosecond timestamps.

I also agree that it must be displayed as standard.

That means

Current behavior only with stat command:
stat /
159 2 drwxr-xr-x 25 root wheel 1048 512 "Feb 24 19:25:21 2021" "Mar 27 02:39:54 2021" "Mar 27 02:39:54 2021" "Jan  1 00:59:59 1970" 32768 8 0 /


Expected behavior:
stat /
159 2 drwxr-xr-x 25 root wheel 1048 512

One may want to create a feature request upstream (OpenZFS) for this
Comment 2 Rich Ercolani 2021-03-27 16:13:38 UTC 
I don't think OpenZFS is the correct upstream for a requested change in stat(1)'s output.
Comment 3 David Schlachter 2021-04-02 01:18:50 UTC 
stat is capable of showing nanoseconds, take a look at Bug 253370. This would just be a question of whether the default format should be changed.

I think here only changing the default format is requested only for stat without additional commands.
