Clock calibration unit, the clock calibration unit is for setting calibration duration T, prover time error t, when timing duration is super
T is crossed, level-one Box server and Host server are subjected to system clock calibration；
Judging unit, error is greater than t between the judging unit is used for when calibrated, judges whether current Host server is clock
Source Host server；
Clock synchronization unit, if it is clock source Host server that the clock synchronization unit, which is used for current Host server, one
Grade Box server obtains the system clock of current Host server, carries out the synchronous simultaneously timer of clock and resets, if current Host clothes
Business device is not clock source Host server, then current Host server obtains the system clock of level-one Box server, updates itself
System time and timer clearing.
6. server system BMC clock synchronization apparatus in pond as claimed in claim 5, which is characterized in that the clock alignment
Unit is specifically used for:
Setting calibration duration T=1h, prover time error t=1s；
When timing duration is more than 1 small, level-one Box server obtain Host server system clock and own system clock into
Row compares.
7. server system BMC clock synchronization apparatus in pond as claimed in claim 5, which is characterized in that the judging unit
It specifically includes:
If the system topology of pond server is the topological structure that separate unit Host connects more Box, it is determined that current Host
Server is clock source Host server；
If the system topology of pond server is the topological structure of more Host connection separate unit Box, current ink is obtained
Channel number, judges whether the level-one Box server system time has synchronized, and is then to be determined according to Channel number
Otherwise clock source Host server determines that current Host server is clock source Host server.
8. server system BMC clock synchronization apparatus in pond as claimed in claim 5, which is characterized in that the clock is synchronous
Unit is specifically used for:
If current Host server is clock source Host server, what level-one Box server obtained current Host server is
System clock carries out the synchronous simultaneously timer of clock and resets,
If current Host server is not clock source Host server, current Host server obtains level-one Box server
System clock, updates the own system time and timer is reset.
9. a kind of terminal characterized by comprising
Processor；
The memory executed instruction for storage processor；
Wherein, the processor is configured to perform claim requires the described in any item methods of 1-4.
10. a kind of computer readable storage medium for being stored with computer program, which is characterized in that the program is executed by processor
Shi Shixian method for example of any of claims 1-4.
