Actually you asked how to convert an ASN1_TIME to time_t. The answer in general to that is "you can't" because an ASN1_TIME can express a wider range of dates than a typical 32 bit time_t. If you want to compare an ASN1_TIME to the current time that's a different thing entirely. What OpenSSL does is to convert the time_t into an ASN1_TIME and compares the two ASN1_TIME structures. There is a function called X509_cmp_time() that does the conversion and comparison. It can be fed either a pointer to a time_t with the time to compare against or NULL which uses the current time.
