Perhaps I'm reading the output of ls wrong, but it seems like files were
written in reverse order.

16:40:06.350406655 -0500 /tmp/first.txt
16:40:06.340406654 -0500 /tmp/third.txt
16:40:06.335406654 -0500 /tmp/second.txt
16:40:06.327406653 -0500 /tmp/fourth.txt
16:40:06.304406652 -0500 /tmp/fifth.txt

Running "ls -lt --full-time /tmp/*.txt | sort -k7" should sort it properly.
