Yes, it’s annoying, but it’s historic. I looked into changing this at one point.

<div class="">I recommend using ASN1_TIME_cmp_time_t() (from the master branch) instead, for the results you are expecting.<br class="">

<div class="">According to documentation to the strcmp,</div>

<div class="">The strcmp() and strncmp() functions return an integer less than, equal to, or greater than zero if s1 (or the first n bytes thereof) is found, respectively, to be less than, to match, or be greater than s2. <br class="">

<div class="">It means (and have been met in practice) that X509_cmp_time() returns other values than 1/-1.</div>
<div class="">So it seems reasonable to either update documentation or fix the behavior.</div>
