Abstract
A time synchronization system includes a host system, a BIOS module, a BMC module, and a RTC module. The BIOS module is embedded in the host system. The BMC module is connected with the BIOS module and communicates with the BIOS module. The RTC module communicates with the BMC module and provides time signals to the BMC module. The host system acquires the time signals from the BMC module through the BIOS module.
Claims6
A time synchronization system, comprising:
- a host system;
- a basic input output system (BIOS) module embedded in the host system;
- a baseboard management controller (BMC) module connected with the BIOS module and communicating with the BIOS module;
- and
- a real time chip (RTC) module connected to the BMC module by an I2C bus and in communication with the BMC module and configured for providing time signals to the BMC module, and the host system acquiring the time signals from the BMC module through the BIOS module;
- wherein the BMC acquires the time signals to record the occurrence time of system logs before than the host system.
