I was looking at this question on Maths Meta. There are four answers and I have them sorted by Date Modified (Newest First).
Listed below are the created and last modified dates of the four answers in the order they are presented. \begin{array}{ll} \text{Creation date} & \text{Last modified date} \\ \hline \text{2011-11-23} & \text{2017-04-13} \\ \text{2023-08-05} & \text{Not yet modified} \\ \text{2017-03-14} & \text{2022-10-23} \\ \text{2014-08-07} & \text{2020-06-12} \end{array}
In what sense are these sorted by last modified date? Or, How do I interpret this? It seems that the first one should be last.
The other two sort methods seem to work correctly, i.e. I get what I would expect to see.
