"There is no way or option to override this check." :-)
For now, it will fail hard and abort syncing. So you would have to stop
using CA CERT verification if you want to use an expired cert.
My reason for this is: 1) I wanted to keep the patch simple, we can get
all fancy based on feedback as followup 2) CA CERT verification *did*
fail, and a simple WARNING in the log is bound to be ignored by
everyone. Perhaps we should only continue if you pass in
--IGNORE_EXPIRED_CERTS as a command line option :-).
I mainly wanted to bring in the patch into play before it bit rots.
I still plan to have a second option of SSL cert cehcking that simply
presents a fingerprint and allows you to permanently accept this
certificate, just like mutt (and ssh) do. This option would not care
about expiration dates at all and just look for an unchanged SSL
