Make sure you’re using /bin/cp.

@vitor I was using /bin/cp. ‘which cp’ in the same terminal window I ran the cp command yielded ‘/bin/cp’.

I don’t know what to suggest more. The manpage is clear on what the option should do and I can confirm it does it on my end.

@vitor I have a theory…

 

Maybe Finder's ‘Created Time’ is just what it thinks should be the correct ‘Created Time’ when it reads multiple file attributes… And different programs write the ‘Created Time’ to different attributes. But cp -p only preserves one of the them when copying. May I ask what program created the file you were testing on? Mine was macOS' screenshot feature.

As I linked before, that’s not something you should rely on.

Highly unlikely. Apps don’t typically write those values themselves, that’s what the file system and operating system are for, to abstract those nuances.

It was a screenshot too. Just ⌘⇧4.
