Extend period for "The included OpenPGP keys are up-to-date"
As of now, that tests check validity for the next month. I think that this warns us way too late. We'd better know about this problem with a bigger time margin.
I think everything would be easier if we could make this check for a longer timespan (say: 2 months).
The implementation is trivial, I opened this issue because I wonder what should be the rationale.
