Add a quick stopgap hack for Portal purposes

People want to be able to write a scheduled-release passphrase to demos
to prove that said demos were recorded during a timeboxed event. Ideally
this is something that'd be part of the custom demo data and general RTA
run management stuff that's planned, but of course that doesn't exist
yet. When it does exist, we'd probably want rid of this nonsense, so
it's marked hidden and I don't plan to document it anywhere "official."
It's just here for people who really need it in the short term.
