The title pretty much sums it up.

I've got a situation where I need to have puppet enforce a given state
most of the time, then when a certain flag is present it needs to use a
different state - but only until a certain amount of time has passed, at
which point it needs to go back to the normal state of things.

I've got some ideas on how I can make this happen, but I am looking for
some more sane alternatives.

I have setup a question with details here:
https://ask.puppetlabs.com/question/447/best-way-to-deal-with-temporary-state-changes/

But the short version is I don't want to get up at 0200 to stop services
in prod for developers when they need to update database tables, and I
don't want to have to remember to revoke their access (controlled via
puppetized likewise config) the morning after the changes.
How about instead of using a simple flag in your hiera data, you use a
timestamp (in some form) of when the permissive access is supposed to
expire? When choosing which config to use, the master then just compares
the timestamp to its system date/time. I'd write the comparison as a
custom function, but you could do it in an inline template for proof of
concept.
I did wind up using a custom function (first time writing one, was
relatively painless), but I think on home time rather than work time I will
do a self-modifying solution just as a proof of concept, and to serve as an
example of what NOT to do.
