In GnuPG, how do I set an absolute date for expiry on my key?
The output of GnuPG on how to specify the expiry is missing the option to just enter an ISO date in the form of YYYY-MM-DD. Unlike the help text suggests it would not be valid, it will just work:
Key is valid for? (0) 2015-01-01
Key expires at Thu 01 Jan 2015 00:00:00 CET
