A timestamp helps keep track of the creation or processing time of digital data and provides proof that
the data is unchanged since the date and time of time stamping. The timestamp also provides evidence of the validity of the signature certificate at signing time. Nexus Timestamp Server provides a secure, standards-based, scalable, multi-tenant, high performance, platform agnostic solution for trusted third parties that want to offer a trusted third-part TSA service or for organizations that want a cost-efficient, in-house time stamping solution.
