If you use the function ASN1_TIME_diff you can find the difference in days and seconds between two ASN1_TIME structures so if you set one to the epoch you can then convert the result to time_t. You have to be careful the result doesn't overflow the local time_t. Steve. -- Dr Stephen N. Henson. OpenSSL project core developer. Commercial tech support now available see: http://www.openssl.org
