It looks like sorting on Date Added (⌘8) displays the date and time as a string of numerals (202312061923, for example) whereas the other date sorts show the date formatted as ccyy-mm-dd plus.
I’d like to see a similarly formatted Date Added as well as an option for Date only (without the time).
It would sort by time (added or modified) but the display would show just the date for a simpler view than the date and time list:
In the above case, I’d like to know what date an article was published but not what time I added it to the collection (assuming I added it on the date published).
