There was a problem hiding this comment.
Is NotAfter a UTC or local time? Change to DateTime.UtcNow if it is UTC, or add a comment that it is local and that DateTime.Now usage is intentional.

NotAfter is local time, so I'll add a comment, will look to see if its easy to add a unit test

This PR doesn't have anything to do with the tests failures, its just a performance fix in one scenario, it won't have any functional impact its just follow up to some perf issues we saw from the benchmarks when we had an expired cert |

We saw massive performance hits in the benchmark when we were using an expired cert, due to the validation cache not storing expired certs at all.
Cache expired certs for 2 minutes by default should mitigate this
