Wintimertester 1.1.zip

The tool displays a "Ratio" value. In a perfectly stable system, this ratio should ideally stay at

The UI is minimalist and functional. It features a simple start/stop button and live-updating fields for the different timer values. Compatibility: WinTimerTester 1.1.zip

The readme was mundane. "Measures timer resolution drift. v1.1 fixes QueryPerformanceCounter rollover bug." But the author’s name— J. Corrigan —made her stomach tighten. Jack Corrigan was a ghost in old dev forums. He’d vanished in 2005, same year Microsoft patched a zero-day that used a timer-based side channel to lift BitLocker keys. No one had proven the link, but Corrigan’s name appeared in the exploit’s comments. The tool displays a "Ratio" value

At its core, the application monitors two primary timing mechanisms: the GetTickCount and the QueryPerformanceCounter (QPC). In a perfectly stable environment, the ratio between these timers should be 1.0000. When this ratio fluctuates or deviates significantly, it indicates that the system's high-precision timers—such as the High Precision Event Timer (HPET) or the CPU's invariant Time Stamp Counter (TSC)—are misconfigured or experiencing "drift."
