is anybody aware of some smart-contract that can be used as external "trustable" oracle for no-so-simple scenarios, like for example calculating the number of non-festive days passed since a given date or time-windows.
I'm thinking of some external (trusted) entity that is allowed to fill such calendar and sign when a new day has passed, ...
I'm thinking about use-cases like:
- Some smart-contract internal state change or some payment must be allowed just after 10 working days, excluding weekends.

Oracle sounds complicated and gas gushing approach.
I suggest this:
A special transaction parameter be generated and signed by your own server
The server calculates the days
The information is passed into the smart contract in the transaction payload, as a function parameter
The smart contract verifies that the result is honest by checking the signature of the parameter, so that it was your server that made the calculation
However, for better judgement, I kindly ask you to edit your question and add more background information about your business case.
