When sorting a list of items by date, is it more logical to sort it by the time that each item was modified or the time that each item was created?
I have seen both of these methods used and I'm trying to determine if there is a best practice here. My current thought is that by using the time created, the list of items will change less when a user goes back looking for an item. However for the last modified time, a user will have all of the files they have changed close to the top of the list.
It is definitely clear that both methods have pros and cons, which one more useful?
