I was after the subseconds part of the file timestamp, which ls -T 
doesn't provide.

Although I don't use macOS, as I understand it apfs is supposed to have 
timestamps with nanosecond resolution, which is what we're looking for here.

What is the output of these three shell command sequences?

test configure -nt configure.1; echo $?

test configure.1 -nt configure; echo $?

ls -lt configure configure.1

Can you install GNU Coreutils on macOS and run its 'ls -l --full-time' 
command? Or is there some macOSish utility that will tell you the full 
file timestamps? Maybe "stat" with some options?
