Currently we set the CRL time range to start at 1 second in the past:
However, this creates a window where an agent with a small amount of clock skew can hit the `CRL not yet valid for <host>` message. This affects both acceptance tests, which sometimes hit this condition and end-users.
We should do something about this. Suggestion here is to: a) bump the 1 second to 1 minute, and b) catch this error message out of OpenSSL and wordsmith it a bit to hint at addressing clock skew.
