This is actually a change in semantics introduced here. The
start/expire values were treated as absolute values, eg in
places we pass '1' for expiry time to indicate a time way
in the past. This has now become 1 hour into the future.
This is why the 3 expiry tests were broken.
I pushed the following change to make sure the expiry tests
have times in the past again

Fix TLS context tests with expired certs
commit 5283ea9b1d8a4b0f2fd6796bf60615aca7b6c3e6 changed the
semantics of the 'expire_offset' field in the test case struct
so that instead of being an absolute timestamp, it was a delta
relative to the current time. This broke the test cases which
were testing expiry of certificates, by putting the expiry
time into the future, instead of in the past.
Fix this by changing the expiry values to be negative, so that
the delta goes into the past again.
