+ * \brief Callback for validity date checks.
+ *
+ * The function receives as parameter an arbitrary user-provided context,
+ * and the notBefore and notAfter dates specified in an X.509 certificate,
+ * both expressed as a number of days and a number of seconds:
+ *
+ *   - Days are counted in a proleptic Gregorian calendar since
+ *     January 1st, 0 AD. Year "0 AD" is the one that preceded "1 AD";
+ *     it is also traditionally known as "1 BC".
+ *
+ *   - Seconds are counted since midnight, from 0 to 86400 (a count of
+ *     86400 is possible only if a leap second happened).
+ *
+ * Each date and time is understood in the UTC time zone. The "Unix
+ * Epoch" (January 1st, 1970, 00:00 UTC) corresponds to days=719528 and
+ * seconds=0; the "Windows Epoch" (January 1st, 1601, 00:00 UTC) is
+ * days=584754, seconds=0.
+ *
+ * This function must return -1 if the current date is strictly before
+ * the "notBefore" time, or +1 if the current date is strictly after the
+ * "notAfter" time. If neither condition holds, then the function returns
+ * 0, which means that the current date falls within the validity range of
+ * the certificate. If the function returns a value distinct from -1, 0
+ * and +1, then this is interpreted as an unavailability of the current
+ * time, which normally ends the validation process with a
+ * `BR_ERR_X509_TIME_UNKNOWN` error.
+ *
+ * During path validation, this callback will be invoked for each
+ * considered X.509 certificate. Validation fails if any of the calls
+ * returns a non-zero value.
+ *
+ * The context value is an abritrary pointer set by the caller when
+ * configuring this callback.
