Nice systemd solution, it seems very elegant!

To be clear, my init script is named S00datetime, not 500datetime. It's actually the very first one that runs from rcS. So the date is restored very, very early in the boot process before pretty much everything else.

Now that you mention it I can't see anything other than an "S". Yes, that certainly makes it less of a problem.
