Windows system time GetSystemTime() Granularity: 100 nanoseconds Precision: approximately 10 milliseconds (Approximately 55ms on Windows 95/98/ME, 15ms on Windows NT 3.1.) (Presently reported as 10.0144 milliseconds.) Apparent precision: 0.010066666666666666 seconds Apparent jitter: 0.00014285714285714287 seconds
Windows system time in file time GetSystemTimeAsFileTime() Granularity: 100 nanoseconds Precision: Same as system time Apparent precision: 0.0100144 seconds Apparent jitter: 0 seconds
FYI see ::timeBeginPeriod / ::timeEndPeriod to get Precision down near 1ms on WindowsNT/2K/XP. THis also affects ::Sleep. ----------------- Jeff Flinn Applied Dynamics, International
