SYNCHRONIZATION OF SYSTEM TIME AMONG SMART DEVICES VIA SECURITY PROTOCOL DATA MODEL (SPDM)

Systems and methods provide an Information Handling System (IHS) comprising a host processor module configured to host one or more processors and two or more smart devices, a secure control module configured to host a baseboard management controller, and a secure control interface configured to support communication between the secure control module and the host processor module. The baseboard management controller is configured to retrieve a current time from each of the smart devices, validate the current time for each of the smart devices, identify a selected current time to be applied to each of the smart devices, and send the selected current time to each of the smart devices. The baseboard management controller is a Security Protocol and Data Model (SPDM)-enabled device that uses SPDM messages to synchronize time across IHS components.
