There is a dconf
setting which I think should control this behaviour, but it seems not to have any effect on Nautilus on my 16.04 Ubuntu (Unity desktop), it only affects file-choser windows like the "Open..." or "Save as..." dialogues of most applications.
You can get the current value of this setting using the command
gsettings get org.gtk.Settings.FileChooser date-format
The default is regular
, the other option is with-time
. You change the value with one of the two commands below.
gsettings set org.gtk.Settings.FileChooser date-format with-time
gsettings set org.gtk.Settings.FileChooser date-format regular
I am not sure whether it's a bug that this setting does not affect Nautilus or whether that is by design though. However, unfortunately I could not find anything closer to what you want.
