System-wide time synchronization across power management interfaces and sensor data

摘要

A power management control system for an information handling system is disclosed. The power management control system includes a power management interface bus interfacing a plurality of devices, where one or more of the devices is each associated with a time clock. The power management control system further includes a management agent interfacing the power management interface bus. The management agent is configured to: receive a system time; synchronize the one or more time clocks based, at least in part, on the system time; and maintain synchronization of the one or more time clocks, at least in part, via a set of telemetric primitives.
