Embodiment
As shown in Figure 1, be the hardware structure figure of managing time of substrate management controller of the present invention system preferred embodiment.This managing time of substrate management controller system (hereinafter to be referred as " time management system ") 12 installs and runs in the baseboard management controller 10 on the motherboard 1, this baseboard management controller 10 also comprises baseboard management controller real-time clock 14, and this baseboard management controller 10 links to each other by the I2C bus with main system real-time timepiece chip 16.Described baseboard management controller 10 is a kind of small-sized separate type processors, be used to monitor and management host plate 1 on the state of each object.
Described time management system 12 is used for when this baseboard management controller 10 divides the os starting of position, get Date and the time from main system real-time clock 16, and the acquiescence date and time of baseboard management controller real-time clock 14 is updated to the date and time of the main system real-time clock 16 that is obtained.
As shown in Figure 2, be the functional block diagram of managing time of substrate management controller of the present invention system.Described time management system 12 comprises opening module 120, acquisition module 122, judge module 124 and update module 126.
Described opening module 120 is used for when motherboard 1 energized, and the hardware on the initialization baseboard management controller 10 starts the operating system of dividing the position on this baseboard management controller 10.
Described acquisition module 122 is used for obtaining date and time from baseboard management controller real-time clock 14 when dividing the os starting of position on the baseboard management controller 10.The form of described date and time can be: 2000 01 month 00: 00: 00 on the 01st Christian era.Described 14 Timing Greenwich Mean Time of baseboard management controller real-time clock section, for example: can timing from 1970 01 month 00: 00: 00 on the 01st Christian era the time to 2010 01 month 00: 00: 00 on the 01st Christian era.
Described judge module 124 is used to judge whether the date and time that obtains from baseboard management controller real-time clock 14 is the date and time of acquiescence.When baseboard management controller 10 outages, baseboard management controller real-time clock 14 stops counting, and when re-powering, this baseboard management controller real-time clock 14 begins reclocking from the date and time of acquiescence.In general, the date and time of this acquiescence is meant the zero-time of baseboard management controller real-time clock institute timing time section, for example can be 1970 01 month 00: 00: 00 on the 01st, and the date and time of this acquiescence general and current date and time is not inconsistent.
Described acquisition module 122 is used for getting Date and the time from main system real-time clock 16 when the date and time that obtains from baseboard management controller real-time clock 14 is the date and time of acquiescence.Described 16 Timing Greenwich Mean Time of main system real-time clock section, for example: can timing from 1970 01 month 00: 00: 00 on the 01st Christian era the time to 2010 01 month 00: 00: 00 on the 01st Christian era.Described main system real-time clock 16 is used for current date and time is carried out real time record.
