Abstract
This document defines requirements for a baseline time-stamp policy
for Time-Stamping Authorities (TSAs) issuing time-stamp tokens,
supported by public key certificates, with an accuracy of one second

defined in this document. Such a policy shall incorporate or further
constrain the requirements identified in this document.
