You all might have used CTime or CTimeSpan to manipulate the system timer. Here is an article to show you how your system timer works. I will give you an idea of port communications behind the system clock manipulations. Those who are a little biased on hardware and software interfacing practices would find this article of great help.

说明：  使用FFT分析方波信号的频谱，讨论采样点数、采样频率对谱分辨率的影响。对数据叠加白噪声后再次分析实验结果。(Square-wave signal using the FFT spectrum analysis to discuss the sampling points, the sampling frequency of the impact of spectral resolution. White noise superimposed on the data after analysis of experimental results.)
