 For the purpose of computing Certificate Validity Periods and CRL and OCSP Validity Intervals, one hour is defined to be exactly 3,600 seconds, and one day is defined to be exactly 86,400 seconds, ignoring leap-seconds. Any amount of time greater than this, including fractional seconds, SHALL represent an additional unit of measure, such as an additional hour or an additional day.
