Another option would be to make a configure option to just ignore the

Or just ignore the date unconditionally. After all, when a certificate
check fails due to out-of-validity-period, then you can always "fix"
that by appropriately setting the clock. So for security, in this
application, the date check is outright useless.

I don't think that is an option, because the date check is part of the crypto-api and not a part of the modsign-stuff.

So it's necessary that the crypto-api offers a flag to ignore the dates and another flag to mark such keys as invalid because of the date. The first flag is necessary to load and use the keys, the second flag for (maybe) other users of the crypto-api which might not use such invalid keys.
