• Accuracy and reliability of three submillisecond-timing methods, a function Query PerformanceCounter(), an instruction RDTSC, and a method IReferenceClock::GetTime() was evaluated under the Microsoft Windows operating system. Measuring frequencies of voltage alternation produced by the three timing methods revealed that the QueryPerformanceCounter( function and the RDTSC instruction performed at their expected, nominal frequencies, but that the IReferenceClock::GetTimeO method did not. Then, the QueryPerformanceCounter( function and the RDTSC instruction were implemented in a test program which recorded the clock ticks corresponding to duration generated by an external chronometric computer. Analysis of the counts of the ticks showed that the two techniques have high precision sufficient for submillisecond timing on Winodws PCs.
