| Abstract: | The principle of computer time is described.To correct the system clock frequency and achieve the precise control of computer time,a method of correcting the computer BIOS time interrupt period is brought out,which is based on an external time standard.In addition,the method of the software design and implementation is discussed in detail.The actual test results are cited to verify the rationality and effectiveness of the method,which is the optimal program to calibrate the computer clock by software at present. |
