cp -Pp didn't seem to preserve the timestamp on GPFS.
I'd need access to the system to see why.
I'd test with touch -d '...' to see if the timestamp was honored
Seems to be working when I try it manually:

So I added 'strace' to the "cp" execution inside the test, and also when used
manually, they seem similar (both attached).
I can check more things if you have suggestions.
