Why does it need to be something in openssl?
Ideally because it needs to be as secure as openssl.
I'm after an accurate time duration between two ASN1_TIME values, that is not
dependent on local conditions, or any external libraries.
try timegm in perl, or if it needs to be in C, just adopt the code
which is just a binary search using the gmtime c function.
i.e. you try to set bits to 1, convert to a textual representation
untill you find your value. You do not need to know anything
about leap years.
