Property perf.ms

---

Overload

Gets the number of milliseconds elapsed since Windows startup. Uses the high-resolution system timer (API QueryPerformanceCounter).

public static long ms { get; }

Property Value

long

Remarks

This function is used to measure time differences with 1 ms precision, like var t1=perf.ms; ... var t2=perf.ms; var diff=t2-t1;. The return value equals perf.mcs/1000 but is slightly different than of System.Environment.TickCount64 and most Windows API. Never compare times returned by different functions. Independent of computer clock time changes.
