Looking at the doc for a (deliberately) old "date", I can't find any mention of the -d "@..." syntax. I take it the command would fail on that system. It would then go on to try the -r variant, which has entirely different meaning on GNU (Linux) systems. docs/ being subject to configuring, why don't you determine the capabilities of "date" there and invoke just the one command that was found suitable for the system?
