This should be moved to Bug Reports, as I'm seeing this in 7.53 but not in 7.52
I hadn't even noticed there *was* a date column, because the log window is too narrow for the columns, and even when you drag the unused 'folder' column narrow, it's back to being fat again the next time you open the log window.
I do see it sorted by size after clicking on that column header, but there's no effect from clicking on the date column.
In older versions there used to be a dropdown menu to select the sort order, but that's gone.
