I'll try to explain it better.
If I have several notes updated during the same day, let's say Mar 10 - I won't see any difference - Evernote will just show "Mar 10" in the column. Legacy version of EN always showed time, now it's not the case. And for notes updated/created earlier than today and yesterday it always used the same format of "dd.mm.yyyy hh:mm:ss" which was way more convenient for me.
