Understanding GetSystemTimePreciseAsFileTime on Windows 7: Update Requirements and Workarounds

: If you encounter this error, look for an older version of the software. For example, Aseprite v1.3.9.2 Strawberry v0.9.3 are known stable versions for Windows 7. Developer Workaround : If you are coding, you should use GetSystemTimeAsFileTime System time adjustments (NTP, manual changes) after Step

timeBeginPeriod(1); // Set to 1 ms GetSystemTimeAsFileTime(&ft); timeEndPeriod(1); System time adjustments (NTP

VOID GetSystemTimePreciseAsFileTime( LPFILETIME lpSystemTimeAsFileTime );

System time adjustments (NTP, manual changes) after Step A will make synthesized times drift relative to actual UTC; to mitigate, periodically resample the base pair (baseFileTime + baseQpc).
QueryPerformanceCounter source may vary across systems (TSC/HPET/APIC), but modern Windows provides consistent behavior; still test on target hardware.
This technique yields high resolution but not authoritative wall-clock updates when the system clock is stepped.

Windows 8

The function GetSystemTimePreciseAsFileTime is not available on Windows 7; it was first introduced in . Because Windows 7 has reached its official end of life, Microsoft has not released an update to backport this specific function. Understanding the Compatibility Gap
